The Aquanauts

The Aquanauts (later known as "Malibu Run") was an ABC network adventure/drama series written by E.M. Parsons.

The show aired from September 14, 1960 to June 7, 1961, lasting for one season & 32 episodes. It was produced by Ziv-United Artists.

Plot
The series centered on the adventures of two Southern California divers, Drake Andrews and Larry Lahr, who made their living salvaging sunken wrecks.

Cast

 * Keith Larsen as Drake Andrews
 * Jeremy Slate as Larry Lahr (1960)
 * Ron Ely as Mike Madison (1961)
 * Charles Thompson as The Captain (1961)

Production
In January of 1961, Keith Larsen left the series due to health problems. His character rejoined the Navy and a new character, Mike Madison (portrayed by Ron Ely) joined the cast.

A month later, the format of the series was also changed with the show's characters, Larry and Mike, opening up a shop in Malibu, California.

No longer encountering underwater dangers, the show's storylines shifted to situations involved on land. To reflect the changes in the format, the show was retitled as "Malibu Run".

Broadcast History
"The Aquanauts" were in competition with the short-lived "Hong Kong" on ABC and "Wagon Train" on NBC.

Unable to compete with the highly rated "Wagon Train", the series was canceled after one season.
