as It Came from Beneath the Sea (1955), with effects from Ray Harryhausen. That was produced by Charles H. Schneer who had worked with Katzman for a number of years; Schneer and Harryhausen went on to make Earth vs. the Flying Saucers (1956) for Katzman before Schneer left to form his own unit at Columbia. Katzman still made westerns such as The Gun That Won the West (1955), Seminole Uprising (1955), Blackjack Ketchum, Desperado (1955) and Duel on the Mississippi (1955), swashbucklers like Pirates of Tripoli (1955) and crime films such as New Orleans Uncensored (1955), Chicago Syndicate (1955), The Crooked Web (1955), The Houston Story (1956), Miami Exposé (1956) and Inside Detroit (1956). He also did the occasional thriller like Uranium Boom (1956). His work had an increasing focus on teens, however. Teen-Age Crime Wave (1955) and Rumble on the Docks (1956) were teen-oriented crime films. He also started making musicals again with rockabilly music. In 1955, when Columbia wanted to release the first rock-and-roll musical, Katzman reworked elements from his Gloria Jean musical I Surrender Dear into one of Columbia's biggest hits, Rock Around the Clock (1956) with Bill Haley and His Comets. This cost $300,000 and earned over $4 million. This was followed by Cha-Cha-Cha Boom! (1956), Don't Knock the Rock (1957, again with Bill Haley), Calypso Heat Wave (1957) and Juke Box Rhythm (1959, scheduled for Bill Haley but ultimately made with singer Jack Jones). Katzman also produced horror films for the teenage audience, including The Werewolf (1956), The Man Who Turned to Stone (1957), The Giant Claw (1957), Zombies of Mora Tau (1957) and The Night the World Exploded (1957). In May 1957 Katzman told Variety that he felt, “A picture that makes money is a good picture —- whether it is artistically good or bad. I’m in the five and dime business and not in the Tiffany business. I make pictures for the little theatres around the country.” He added that his movies were normally budgeted between $250,000 and $500,000. He said at Columbia he had made 110 pictures, none of which lost money, and the average gross was $1 million. He said at least 40% of the 110 pictures made were still in release. “Every picture I make now has a selling gimmick aimed at the young audience," he said in 1957, and he made car movies, horror stories, science fiction and music.
