Many believe that the 1970s decade changed the film and television industry.

With iconic films like The Godfather I and II, Star Wars: Episode IV, Jaws and Grease all released in the decade, it’s hard to argue it wasn’t a great time for the industry.

With great films come great actors and actresses. Here’s some of the most iconic movie stars of that decade and what they are up to now.
