Peter Helm, the actor from Toronto who appeared on such 1960 shows as Naked City, Wagon Train and Ironside and in films including The Longest Day, Inside Daisy Clover and The Andromeda Strain, has died. He was 84.

Helm died Thursday in his sleep at his home in West Hills, his friend David Timmerman told The Hollywood Reporter.

Survivors include his sister, actress Anne Helm (Follow That Dream, The Magic Sword, The Iron Maiden), and a daughter, actress Tiffany Helm (Friday the 13th: A New Beginning).

The colorful Helm appeared alongside Jane Fonda, Dean Jones and Joey Heatherton on Broadway in 1960 in the Josh Logan-directed There Was a Little Girl, a drama about rape, then acted onstage with Myrna Loy in a 1962 production of James Kirkwood’s There Must Be a Pony that aimed for Broadway but missed.

He and Heatherton would enjoy a great friendship while traveling the world together over the years, and she told THR that he was “a great actor and a great person, top of the world.” The pair also worked with George Carlin at the start of his career, and the comedian once called Helm one of the funniest men he had ever met.

On the big screen, Helm portrayed an ill-fated G.I. in the Darryl F. Zanuck-produced The Longest Day (1962) and the social climber Milton Hopwood opposite Natalie Wood in Robert Mulligan’s Inside Daisy Clover (1965), then sent the sci-fi plot in motion as one of the two Air Force officers who spot a U.S. satellite going down in Robert Wise’s The Andromeda Strain (1971).

Peter John Helm Jr. was born on Dec. 22, 1941. After the death of his banker father, John, his mother, Isabel, brought his older sister to New York in 1952 to support her ballet ambitions, and he and his half-brother, David, came along.

Helm made his onscreen debut on a 1959 episode of the NBC sitcom Too Young to Go Steady, then showed up as fresh-faced types on such series as Dr. Kildare, The Donna Reed Show, Tales of Wells Fargo, Naked City, Rawhide, The Fugitive, Combat!, Mr. Novak, The Farmer’s Daughter, Perry Mason and Bonanza through the mid-1960s.

His final onscreen credit came on a 1971 episode of The Smith Family.

In 1991, Helm founded Vancouver-based GeoMediapro, working as a director and producer, and he taught at the Vancouver Film School and was a Teamster for more than 20 years. Away from show business, he was an enthusiastic aviation photographer and the founder of a Ferrari club in L.A. who liked to drive fast.

His first wife was actress Brooke Bundy (two Nightmare on Elm Street films); they were married from 1962 until their 1966 divorce. His survivors include another daughter, Brandee, and seven grandchildren. His son, Dustin, died of complications from a motorcycle accident in 2014.
