The hour-long series focuses on the adventures of two
Southern California divers, Drake Andrews (Larsen) and Larry Lahr (Slate), who made their living salvaging sunken wrecks. In January 1961, Larsen left the series due to health problems. His character rejoined the
Navy and a new character, Mike Madison (Ron Ely), replaced him. A month later, the format of the series was also changed with the show's characters, Larry and Mike, opening up a dive shop in
Malibu Beach. While still engaged in dangerous underwater salvage dives, the partners' youthful lifestyle and romantic encounters were given more emphasis. To reflect the changes in the format, the series was retitled
Malibu Run, with a lively theme performed by pianist
André Previn. The program was broadcast on Wednesdays from 7:30 to 8:30 p.m. Eastern Time in competition with the short-lived
Hong Kong on
ABC and
NBC's
Wagon Train. Unable to compete with the latter show, the series was canceled after one season. ==Cast==
