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 and a huge number of big-name cameo appearances.
