c) Lagaan: No guns, but lots of horses and lots more cricket. Like China Gate before, (and, years earlier, Yul Brynner's Magnificient Seven), clearly inspired by Kurosawa's The Seven Samurai. Except that, it's set in the British Raj, and amidst dust, guns and cross-racial romance, ends in an exciting, international cricket match.
OTOH, you want to grab something on a (an Indian) theater near you, Chak de India is a good bet. Haven't seen it myself, but apparently has is an interesting commentary on women's empowerment, intra-national cultural clash and field-hockey.
I'm no expert, but in my limited experience it depends very much on what you mean by "really good". I've seen four or five, and they've all been incredibly formulaic, unintentionally campy, and interminable. They all also espoused dubious and antiquated values about gender roles.
That said, a lot of the singing and dancing is fabulous. I particularly enjoyed some of the numbers in Gumnaam, which is the movie Thora Birch is dancing along to at the beginning of Ghost World. Actually, give me a minute, and I'll try and dig up the song she's dancing to, which is, if you'll pardon my french, fan-fucking-tastic.
