Singing, Dancing Robots in Bollywood Feature
If you thought that The Terminator didn't have enough singing and dancing, then maybe you'll want to check out S. Shankar's Endhiran. This Bollywood sci-fi epic features the requisite song-and-dance numbers alongside some overblown action sequences and (we can only assume) a comically chaste romantic subplot.
I should point out that the film isn't technically a Bollywood film. It's actually part of the Tamil film industry, known coloquially as Kollywood (apparently). But, you know, it fits that whole Bollywood aesthetic, and we all know Bollywood is just a state of mind, right?
