20 Years of Pyaar Ke Side Effects: Rahul Bose Says Mallika Sherawat’s Casting Changed the Film

Two decades after Pyaar Ke Side Effects brought Rahul Bose and Mallika Sherawat together in an unconventional romantic comedy, the actor has revisited the making of the film and explained how Mallika's casting influenced its characters, dialogues and overall flavour.

In an exclusive interview with Bollywood Hungama published on November 2, 2026, Rahul recalled that director Saket Chaudhary's decision to cast Mallika led to fresh discussions about the way the characters would speak and behave. He described the actress as a delight to work with and praised her hard work and comic abilities.

Released in September 2006, the film paired Rahul as Siddharth, popularly known as Sid, with Mallika as Trisha. Its story explored the complications of commitment, relationships and marriage through the perspective of a man who enjoys being in love but becomes anxious when marriage enters the conversation.

How Mallika Sherawat’s Casting Changed the Characters?

Rahul explained that Mallika's casting was not simply a decision about who would play the female lead. It influenced how the writing team approached Trisha and her interactions with Sid.

He recalled that after Saket Chaudhary decided to cast Mallika, the director and Rahul discussed changes to the dialogues and the character's personality. Trisha was shaped as a Punjabi woman from Delhi, while Sid was imagined as a South Mumbai man. Their contrasting backgrounds became an important part of the film's humour.

Rahul also recalled that the character's comfort with alcohol and her relatively straightforward approach to language became part of the conversations around the role.

The actor described the filmmaking experience as collaborative, adding that he and Mallika shared a friendly working relationship throughout the shoot.

His recollections offer an interesting look at how casting can influence a screenplay even after its central story has been established. In this case, the contrast between the two lead characters became one of the film's defining comic ingredients.

Rahul Bose Praises Mallika Sherawat’s Performance

Rahul was particularly appreciative of his co-star's contribution. Calling her a delight to work with, he remembered her as someone who brought energy to the set and worked hard on her performance.

The casting was also significant in the context of Mallika's screen image at the time. Following films such as Khwahish and Murder, she had become widely associated with bold roles. Pyaar Ke Side Effects gave her an opportunity to explore a different kind of character, one whose humour, confidence and personality were central to a relationship-driven story.

The film's production company, Pritish Nandy Communications, lists Rahul Bose and Mallika Sherawat among its principal cast, with Saket Chaudhary as director and Pritish Nandy and Rangita Pritish Nandy as producers.

The Fourth-Wall-Breaking Style That Made the Film Different

Another aspect Rahul revisited was the film's use of the fourth wall. His character Sid frequently addressed the audience directly, making viewers part of his personal dilemmas and comic observations.

Rahul said he was familiar with this technique through his stage experience and earlier films, including English, August and Mumbai Matinee. He felt that the writing of Pyaar Ke Side Effects used the device particularly cleverly.

The approach helped give the romantic comedy a conversational quality. Instead of allowing the audience to remain distant observers, Sid's direct exchanges made his anxieties and excuses part of the viewing experience.

The film also featured Ranvir Shorey as Sid's friend, adding another layer to the protagonist's attempts to understand relationships and commitment.

Rahul Bose Remembers the Audience Response

Rahul also recalled receiving videos from friends and well-wishers who watched the film in theatres. They would show him audiences laughing and share comments about how the situations on screen reminded them of their own relationships.

He remembered people telling him that their husbands or wives recognised themselves in the characters. For Rahul, these reactions suggested that the film had connected with viewers through its familiar relationship situations and humour.

That response is particularly relevant to the film's anniversary. Its premise was rooted in a recognisable conflict: the difference between enjoying a relationship and being ready to make a lifelong commitment.

Will Pyaar Ke Side Effects Get a Sequel?

With the film completing two decades, the conversation naturally turns to whether Sid and Trisha could return to the screen.

When the possibility of a sequel was raised during the interview, Rahul responded with humour, joking that if the makers waited any longer, it would have to be called Maut Ke Side Effects.

The remark was a playful response to the passage of time, not an announcement that a sequel is in development.

The franchise did, however, continue with Shaadi Ke Side Effects, released in 2014. The film brought back director Saket Chaudhary but introduced Farhan Akhtar and Vidya Balan as the central couple. Pritish Nandy Communications' official announcement described it as a sequel to the 2006 film, with the lead casting changing from Rahul and Mallika to Farhan and Vidya.

The Celebrity Hour Take

The anniversary interview highlights an important part of what made Pyaar Ke Side Effects distinctive: its casting was closely connected to the film's writing and comic identity.

Rahul's recollection suggests that Mallika's interpretation of Trisha helped shape the character rather than simply filling a role already defined on paper. The contrast between Sid and Trisha gave the film a particular rhythm, while the fourth-wall-breaking narration allowed its humour to feel direct and personal.

Twenty years later, Rahul's memories also bring attention back to the creative collaboration behind the film. His comments are not just a nostalgic tribute to a former co-star; they offer a glimpse into how performance, casting and writing can influence one another during filmmaking.

Pyaar Ke Side Effects remains a notable chapter in the filmographies of Rahul Bose and Mallika Sherawat, and its anniversary has provided an opportunity to revisit the unusual pairing that helped define its identity.
