Fruit & Nut is one of those movies you just have to give yourself over to. It is incredibly silly. My favorite bits were the old man dance sequence and when the transvestite mob, mobs our hero in a street dance sequence.
The story line is, well, ridiculous, but enjoyable. Basically a doofus who reminds me a lot of a cute chubby Indian version of Fred Armisen manages to get himself embroiled in a plot to destroy Mumbai and somehow manages to doofus his way through to solving the case. He is super cute in his doofusness. However, this movie is so silly, it really is impossible to predict how or where this movie will go. Just go along for the ride and enjoy it.
What you should know is that this is a Bollywood movie, so it's in Hindi with English subtitles. It's also a musical. On the plus side, it's only about 1 1/2 hours long, so rather short for Bollywood. But, if you like silly Bollywood musicals, you'll like this movie.
