Action Replayy is a 2010 Indian Hindi-language science-fiction romantic comedy film directed by Vipul Shah and starring Akshay Kumar and Aishwarya Rai in the lead roles. Aditya Roy Kapoor, Neha Dhupia, Rannvijay Singh, Om Puri, Kirron Kher and Rajpal Yadav play supporting roles in the film. The plot is almost identical to the 1985 film Back to the Future. Director Vipul Shah however insists that it is an adaptation of a Gujarati play of the same name and of H. G. Wells’ 1895 novel The Time Machine.

The film follows a young man named Bunty, who enlists the help of his girlfriend’s grandfather, a scientist, when his parents are about to part away. With the help of a time machine created by the scientist, he travels back to 1975 when his parents were unmarried, and tries to make them fall in love.

The film was released theatrically on 5 November 2010, coinciding with Diwali.
