Beau Starr, who appeared in “Goodfellas” and multiple “Halloween” movies has died at the age of 81.

His younger brother, Mike Starr, told TMZ on Saturday that Beau died “peacefully of natural causes” on April 24 in Vancouver, Canada.

Mike — who is also an actor — said Beau was “very unique and special.” He also divulged that Beau was a significant influence on him, even helping raise him, along with their parents.

Christopher Serrone — who played young Henry Hill opposite Beau as his father in “Goodfellas” — paid tribute to him via Instagram on Saturday.

“It is with a heavy heart Im here to inform everyone of the very sad passing of Beau Starr,” he wrote, noting that Mike asked him to “make the announcement. 

“Beau enjoyed a rich [and] meaningful life,” the statement continued. “He was a son, brother, father, grandfather, actor and NFL/CFL player. Please take a moment to help me remember a great guy. RIP.”

Born in New York City in 1944, the actor initially embarked on a career as an athlete — playing on the New York Jets practice squad for three seasons, and completing two seasons with the Canadian Football League’s Montreal Alouettes and Hamilton Tiger-Cats.

He launched his acting career by appearing in the 1980 play “The Set-Up” at the American Theater of Actors, and starring in 1980s television series including “True Blue” and comedy sketch show “Rituals.” 

His best-known television role was as Lieutenant Harding Welsh of the Chicago Police Department in TV’s “Due South” in the 90s.

The actor showed up in guest appearances on hit series including “NYPD Blue,” “T.J. Hooker,” The A-Team,” “Hill Street Blue,” “Knight Rider,” and “V: The Series.”

Beau first appeared on the big screen alongside acting icons Gilda Radner and Gene Wilder in 1982’s “Hanky Panky.”  

Roles in the 1987 comedy “Summer School,”  Martin Scorsese’s iconic “Goodfellas,” and 2005’s “Cinderella Man” followed.

He’s also beloved for back-to-back turns in classic horror franchise installations “Halloween 4″ and “Halloween 5.”
