Aron Kincaid, who appeared in many of the popular beach party pics of the 1960s, died Jan. 6 in Los Angeles of heart failure. He was 70.

Kincaid was featured in “The Girls on the Beach,” “Beach Ball,” “Ski Party,” “The Ghost in the Invisible Bikini” and “Dr. Goldfoot and the Bikini Machine.” At one time he was so popular that his fan mail was reportedly more than that of Frankie Avalon or Annette Funicello.

Born Norman Neale Williams II, Kincaid made a few uncredited appearances in films including Roger Corman’s 1959 “The Wasp Woman” and 1960’s “Spartacus” even while in college. Leonard Freeman also used the thesp as Noreen Corcoran’s b.f. in 1957’s “The Bachelor Father.”

After graduating from UCLA, Kincaid went into the Coast Guard Reserve, but with his height, blond hair and tan, he was a natural for the party pics starting with 1965’s “The Girls on the Beach,” at Paramount. Pic, co-starring Corcoran, included music from the Beach Boys and the Crickets. That same year he appeared in Edd Byrnes-Chris Noel starrer “Beach Ball,” with music by the Supremes and the Righteous Brothers, and the Frankie Avalon-toplined “Sky Party,” with tunes by James Brown and Lesley Gore. He was signed to American Intl. Pictures and appeared in “The Ghost in the Invisible Bikini” and “Dr. Goldfoot and the Bikini Machine.”

Released from the studio contract, Kincaid appeared in pics including 1967’s “The Happiest Millionaire,” 1972’s “The Proud and Damned” and 1976’s “Cannonball.”

On TV, he guested on series including “My Three Sons,” “The Beverly Hillbillies,” “Get Smart” and “Lassie.”

Eventually, he tired of showbiz and retired to San Francisco to become a painter but returned to model and work in commercials including acting as a spokesmodel for Schick products and Cadillac.

In the 1980s Kincaid turned to voiceover work for toons including “The Smurfs,” “The Animated Teenage Mutant Ninja Turtles” and “Walt Disney’s Duck Tales” and vidgames including “Star Wars: Jedi Knight II — Jedi Outcast.”

He also had recurring roles in “The Transformers” and 1992’s “Batman” animated series.
