If you watched The World's Fastest Indian, (and who didn't?) You'll recall some famous actors were in supporting roles... like Walter Goggins. But did you know who the tall guy was in scenes at Benneville? Peter Lawford's son.

He's also JFK's nephew. Hows that for something crazy you didn't know?  I just learned when reading through https://www.looper.com/115801/actors-lost-2018/sl/christopher-kennedy-lawford

Not surprisingly, growing up as a son of the Rat Packer, he was living a life of wealth and privilege, but with a rough start... both uncles assassinated, and his parents divorced. He may have had little chance for a sober life, and he zoomed into illegal drugs, then got a law degree, then followed in his dads footsteps to Hollywood's siren song. 

his many acting roles included the soap operas General Hospital and All My Children, sitcoms like Frasier, and even Tales from the Crypt. His film work included The Doors, and Thirteen Days

He died of a heart attack last month.
