Paramount Pictures is an American film studio founded in 1916 that has become one of the largest studios in the world. It helped pioneer the concept of marketing films nationally and internationally. Some of Paramount's most successful films include The Firm from 1993, Marathon Man from 1976, and The Godfather from 1972, which was one of the studio's greatest achievements and highest grossing films. The production process at Paramount follows standard steps - pre-production, filming, post-production, distribution, and marketing. Paramount and other studios must also adhere to regulations from classification boards like the BBFC that assign age ratings to films.
