I have attempting to get hold of this film for a very long time and when i finally got it wow. However several bits did not make sense. The previous reviews says it is 142 minutes long, and i know for a fact that at least one of the five songs was missing - 'Teri hai zameen, tera aasman'. Having done a further search, the film is actually 185 minutes long. Although the film was great, the reason it did not make sense was because i'd seen the edited version, where they had taken out all the important bits.
The songs are absolutely great, the relationship between Vinod Khanna and Praveen Babi, and Dhamendra with Hema Malini was great, especially where they got together.
Still attempting to get hold of a proper copy so if anyone knows where then please let me know.
