Vidhu Vinod Chopra says the transition from Bollywood to Hollywood is like mastering a ''different artform''.

The 62-year-old Indian film-maker - who's helmed some of the biggest movies in Indian cinema, including '3 Idiots' and 'PK' - performed the roles of director, writer and producer for the new American mystery thriller 'Broken Horses' and says making an English-language film is dramatically different from Bollywood.

Speaking exclusively to BANG Showbiz, Vidhu explained: ''It's very, very different. It's like a completely different artform.

''Indian cinema, Bollywood cinema, it's all slightly over the top, whereas when you do a western film it's completely different.''

Vidhu claimed Hollywood doesn't have a great deal of respect for its Indian equivalent but hopes attitudes might change in light of 'Broken Horses'.

He reflected: ''Bollywood is actually looked down upon, clearly.

''I mean the West doesn't give Bollywood its due. Because they look down upon Bollywood, that's why it's important to do this film. That's the point I'm making: We guys can do movies as good if not better than those guys can.

''Going by the reaction we have so far, from various film-makers and critics responding to the film, we can do it.

''We just have a different artform that we cater to. But that doesn't mean that we can't master this other artform that we've done for the first time in 'Broken Horses'.''
