Bollywood and Tollywood are two different film factory. They are not competitor. But Bollywood is obviously better than tollywood. Because they have better technology, director, producer, actor, actress an so on.
You are wrong sumon. Tollywood have also a better technology like Eega Movie, best directors like Rajamouli, Puri Jagannadh and number of directors have. Tollywood have best actors from Sr. NTR to Jr.NTR. Bollywood is the National film industry and Tollywood is the state film industry, this is the only difference between these two industries. See number of Tollywood films are going to remake in Bollywood.
Tollywood is best cos they have new ideas and new stories but Bollywood just have one talent that is copy.....
I have been watched some of the bollywood movies but not yet i didn't watch any tollywood movies. so i am unable to find out which one is best.
