The recently unveiled first-look poster for the upcoming Bollywood film 'Ek Din,' starring Junaid Khan and Sai Pallavi, has generated significant online backlash. Released on Thursday, January 15, 2026, the poster quickly became a topic of discussion across social media platforms, especially Reddit, with many netizens accusing the makers of a lack of originality. Critics pointed out a striking resemblance between 'Ek Din's promotional artwork and the poster of the 2016 Thai romance drama 'One Day', of which 'Ek Din' is reportedly an official remake. Social media users specifically highlighted comments such as, 'Remake of Thai movie- original movie ke poster hi use kiya hai. Title bhi wahi translate karke utha liya' (They used the original movie poster and translated the title as is), suggesting that both the visual design and the Hindi title are direct lifts from the original Thai film. While a section of the audience defended the poster, expressing excitement for the lead pair's chemistry, the dominant sentiment online has focused on the perceived unoriginality. 'Ek Din' marks Sai Pallavi's debut in Hindi cinema and is produced by Aamir Khan Productions, helmed by Junaid's father, Aamir Khan. The film is directed by Sunil Pandey and is slated to hit theatres nationwide on May 1, 2026. The controversy has sparked a debate ahead of the film's release, questioning the creative choices in remakes.
