Delhi Belly's rare singing-and-dancing production numbers play classical Bollywood glitz for pure kitsch, the Ram Sampath–composed soundtrack otherwise tending toward up-tempo sing-along rock, including a hit song ("DK Bose") with a subliminally dirty chorus.

A smartly paced, highly entertaining Bollywood gagfest. No comic masterpiece, perky pic nevertheless boasts likable characters, colorful villains, well-timed gags and Ram Sampath's extremely catchy tunes, all woven into a seamless, escalating whole.

Akshat Verma's script is imaginative and funny, the film's stars are engaging and Delhi Belly adds up to pleasing escapist fare.

It also shows, perceptively and often sweetly, a broader slice of young, urban, educated life in India as the three deal with careers, love and happiness.

Director Abhinay Deo and producer Aamir Khan's gleeful experiment in "Hangover"-caliber humor delivers the laughs, and its young stars, including Khan's nephew, A-lister Imran Khan, rise to the challenge.
