Robert Opel was severely underdressed when he famously crashed the 1974 Academy Awards.

Well, ladies and gentlemen, that was almost bound to happen, said the actor.

Its one of those one-time things, he said.

It was a social comment, says Opels nephew, Robert Oppel.

In 1979, Opel staged his last piece of performance art.

In May, White was convicted of manslaughter instead of murder.

In protest, Opel dressed in leathers as Gay Justice and fake-executed a friend representing White.

When Opel refused, one fatally shot him.

Oppel believes the crime was connected to his uncles activism and hopes to put his uncles life on screen.

I have a screenplay, says Oppel, who directedUncle Bob, a 2010 doc about his relation.

I think its a great idea for a biopic.

It would be an amazing part.
