Rohit Shetty is good at comedy. The jokes work. But Sunday soon strays into the whodunit zone. The plot too contributes to the mystery. It is non-traceable.

Ayesha Takia is a dubbing artiste in the animation industry. And boy, what a vocal cord! She switches from Mickey to Hanuman to Stuart Little in seconds.

Potential groom Ajay Devgan is an efficient policeman, who relishes bribes, ice-creams and duty, in that order. Suddenly, one Sunday goes missing from Takia’s life. She cannot recollect what happened on that day. She already suffers from critical memory loss (“what was I going to say,” “who was I going to meet”) and the current crisis brings more strangers into her life. (The confusions first made to the screens in Telugu as Anukokunda Oka Roju).

Cabbie Arshad Warsi roams around in his bright-red Amby, but the ride turns a pain after a rogue bullet finds his posterior. Good friend Irfan Khan is a budding actor who does a Ravan, Don, Dracula and a Reshammiya to keep his career rolling.

Together, they do a classic comic act. But it is Irfan who scores with some brilliant bakvaas. Warsi, as usual, is natural, but did we really need that failing kidneys and subsequent wails? And what was Tusshar Kapoor doing on the dance floor? A nanosecond cameo?

You can laugh with Sunday, the comedy is excellent. If only Rohit Shetty hadn’t attempted a thriller...
