Dial 100 (1982)

It is a tragedy that few people know about this gem. It has everything - great random songs, comedy, tragedy, drama, action, betrayal, murder, criminal masterminds, romance, jealousy, siblings reunited, miracles, wonder pets, advanced technology, and memorable dialogue. An amazing Vinod Mehra in his prime (wonder why he never became a big star...?) complements many other stars (Ashok Kumar, etc.) and a huge number of big-name cameo appearances. This movie could very well have been the fountainhead of many of the clichés of Indian cinema. It you can find this movie, watch it (especially with friends) and relive the glory days of Indian masala cinema...!
