Irrfan Khan has played many roles in his film career, but the character in Rohit Shetty's Sunday may be one to remember.

Irrfan plays an unsuccessful actor, who keeps auditioning for roles with little luck. One of his roles include playing Ravana.

The film, which also stars Ajay Devgan [Images], Arshad Warsi [Images] and Ayesha Takia [Images] is about an investigation into a case involving memory loss or more specifically, about a missing Sunday in Sehar's (Ayesha's) life.

Further investigation into the case by ACP Rajveer (Devgan) throws up a whole lot of possibilities and suspects, among whom are the following -- Ballu, the taxi driver (Warsi), his friend, Kumar (Irrfan) and Ritu, Sehar's close friend.

This intriguing puzzle is produced by Kumar Mangat, who produced Omkara [Images] and No Smoking earlier.
