‘Hi’ Trailer: Nayanthara and Kavin’s Unlikely Marriage Takes Centre Stage Ahead of August 28 Release

A postponement has given Hi something more valuable than another two weeks on the promotional calendar: a chance to tell audiences what its unusual romance is actually about.

The Tamil romantic entertainer starring Nayanthara and Kavin was initially scheduled to reach cinemas on August 14, 2026. Its producers subsequently shifted the worldwide theatrical release to August 28, announcing the change through a playful video featuring the two leads.

Now, with the film a week away from release, its trailer has finally opened up the story.

Kavin plays Mayilsamy, a man desperate to find love and settle down. Nayanthara is Devayani, a woman whose attitude towards relationships is considerably different. Their meeting doesn't produce the conventional boy-meets-girl progression Mayilsamy might have imagined.

She rejects him.

And somehow, they still end up married.

The trailer turns that contradiction into the film's central question: can a marriage created under unusual circumstances eventually become a relationship built on genuine love? 

Hi was supposed to release on August 14

Before the trailer arrived, the film's release-date change had been its biggest development.

The producers had previously announced August 14, 2026 as the theatrical date after the film completed its certification process.

On August 7, that plan changed.

Rowdy Pictures' official announcement asked audiences to instead mark August 28, describing Hi as its heartwarming entertainer for the season. Daily Thanthi preserved the production house's announcement in its contemporary coverage.

The announcement itself did not specify a detailed reason for the postponement.

That distinction matters.

Several reports connected the change to the crowded August 14 theatrical calendar, but unless the producers explicitly identify avoiding competition as the reason, The Celebrity Hour should not state that as an established fact.

The confirmed information is simpler:

August 14 was the earlier date. August 28 is the revised date.

BookMyShow currently lists the film for August 28 as well.

The trailer finally introduces Mayilsamy and Devayani

The newly released trailer changes what audiences know about Hi.

Mayilsamy, played by Kavin, hasn't had much success finding a partner. His search eventually leads him to Devayani, played by Nayanthara.

He develops feelings for her.

Devayani doesn't reciprocate in the way he expects.

Instead, the trailer presents her as someone unwilling to conform to the romantic expectations surrounding her. Mayilsamy consequently finds himself facing another rejection.

That could have been the end of their story.

Instead, circumstances bring the pair into an unexpected situation that results in them getting married.

The marriage therefore isn't presented as the happy ending.

It appears to be where the film's real relationship story begins.

Can one-sided love survive a marriage?

That reversal is what makes the trailer more interesting than its basic romantic-comedy packaging initially suggested.

Mayilsamy enters the relationship already emotionally invested in Devayani.

Devayani doesn't appear to begin from the same place.

The film can therefore explore a question mainstream romances usually resolve before marriage rather than afterwards: what happens when two people enter the same relationship with completely different emotional expectations?

BookMyShow's current synopsis similarly describes the protagonists as two people with opposing beliefs about love who are pushed into an unexpected and awkward situation. Their experiences then force both outside their comfort zones as they discover what loving and being loved means.

That suggests Hi isn't simply interested in whether Mayilsamy can “win” Devayani.

The more meaningful question is whether the relationship changes both of them.

Nayanthara and Kavin are pairing up for the first time

Hi also marks the first screen collaboration between Nayanthara and Kavin.

That pairing itself gives the project an unusual dynamic.

Nayanthara brings more than two decades of experience across South Indian cinema, while Kavin represents a younger generation of Tamil stars whose profile has grown significantly through contemporary romantic and commercial films.

Instead of hiding that contrast, Hi appears willing to use the difference in their screen personalities.

Kavin's Mayilsamy comes across as openly eager to find love.

Nayanthara's Devayani appears more guarded and independent.

That contrast is more useful to the story than simply placing two stars together and expecting chemistry to do the rest.

Vishnu Edavan makes his directorial debut

Hi is written and directed by Vishnu Edavan, marking his feature-film directorial debut.

That is particularly noteworthy because Edavan has previously been associated with filmmaker Lokesh Kanagaraj's team.

Yet Hi is almost the opposite of what audiences might expect from someone emerging from that filmmaking environment.

There are no gangsters dominating the promotional material.

No elaborate action mythology.

No promise of interconnected universes.

Instead, Edavan has chosen a relationship-driven family entertainer for his first feature.

The film also has additional screenplay and dialogue work credited to C.U. Muthuselvan.

An experienced ensemble surrounds the two leads

The film isn't built solely around Nayanthara and Kavin.

Its ensemble includes Raadhika Sarathkumar, Prabhu, K. Bhagyaraj, Amrutha Srinivasan, VTV Ganesh and Sathyan, among others. BookMyShow's current listing confirms the principal ensemble alongside the two leads.

That cast reinforces the film's positioning as more than a two-character romance.

Family relationships appear likely to play an important role in what happens after Mayilsamy and Devayani's unexpected marriage.

The presence of performers such as Prabhu, Raadhika and Bhagyaraj also gives Vishnu Edavan a veteran supporting cast around his younger central protagonist.

Nayanthara is also producing Hi

There is another important dimension to Nayanthara's involvement.

She isn't only playing Devayani.

BookMyShow credits Nayanthara, Vignesh Shivan and Zee Studios among the film's producers, while contemporary announcement coverage identifies The Rowdy Pictures, Seven Screen Studio and Zee Studios South as the banners behind the project.

That makes Hi both a starring vehicle and a production venture connected to Nayanthara and Vignesh Shivan.

The film has music by Jen Martin, cinematography by Rajesh Shukla and editing by Philomin Raj.

The music has already become part of the film’s identity

Music appears central to how Hi is being positioned.

Jen Martin has composed the soundtrack, continuing his association with Kavin after previous collaborations.

Among the songs promoted ahead of release is Rasagulla, sung by Anirudh Ravichander. Daily Thanthi reported on the song shortly before the revised release-date announcement.

For a relationship-driven film with relatively little dependence on action or spectacle, the soundtrack potentially carries more narrative and promotional weight.

The songs can establish the emotional relationship between Mayilsamy and Devayani before audiences even see the finished film.

The film has already completed certification

Hi has also moved beyond the stage where its release is merely a production target.

The film has received a U/A certificate, according to contemporary coverage of its certification and revised theatrical plans.

BookMyShow currently lists a runtime of approximately 2 hours and 24 minutes and categorises the film across comedy, drama, family and romance.

With the trailer now released and August 28 still appearing across current theatrical listings, the promotional campaign has entered its final phase.

August 28 gives Hi a different theatrical position

It is tempting to say the postponement was specifically designed to avoid competition.

The available official announcement doesn't establish that.

What can be observed, however, is the practical result.

Moving from August 14 to August 28 removes Hi from its original Independence Day weekend position and gives the film a separate launch later in the month.

That can matter for a romance built more around performances, music and family appeal than large-scale spectacle.

A two-week delay isn't necessarily significant for the film itself.

But it changes the theatrical environment in which audiences first encounter it.

Whether that ultimately benefits the film commercially will only be measurable after release.

The Celebrity Hour Take

The most interesting thing about Hi is no longer its postponement.

It's the relationship the trailer has finally revealed.

Indian romantic films have spent decades turning marriage into the destination: two characters meet, fall in love, overcome opposition and eventually end up together.

Hi appears to scramble that sequence.

Mayilsamy finds Devayani.

He falls for her.

She rejects him.

Then they somehow get married.

Instead of asking whether the couple will reach marriage, Vishnu Edavan can now ask the harder question: what happens after two people who don't feel the same way are suddenly expected to behave like a couple?

That gives Nayanthara's character particular importance.

If Devayani exists simply to eventually reward Mayilsamy's persistence, the premise risks becoming familiar.

But if the film gives her perspective equal weight — why she views relationships differently, what she wants from the marriage and whether her feelings change on her own terms — Hi could become a more interesting examination of companionship rather than another pursuit-driven romance.

The casting helps.

Kavin can bring the vulnerable, slightly awkward quality Mayilsamy requires, while Nayanthara has enough screen authority to prevent Devayani from feeling like merely the object of his affection.

The August 28 postponement bought the film another fortnight.

The trailer has now revealed what the film needs to sell during that time:

Not simply Nayanthara and Kavin together.

But two people who shouldn't logically be together trying to understand what their marriage actually means.

Sources & Verification

This report was independently prepared using the producers' publicly reported August 7 release-date announcement, the newly released Hi trailer, current theatrical information from BookMyShow and contemporary coverage of the film's certification, cast and production credits. The August 28 date is currently supported by both the makers' announcement and live theatrical listings. No specific motive for postponing the film has been presented as confirmed because the official release-date announcement did not provide one.
