Quiz Question: If I may? Who Am I?

Hey Guys,

I don't normally participate, mainly because my knowledge on Flynn is pretty limited but I do have a question.

Who Am I?

I was born in Boston, Massachussets, the youngest of three brothers; all of whom worked in the movie industry. I made close to 200 films during a very varied career and worked with Errol Flynn.
My middle name is Waldo.

More clues if needed.

best wishes,

Brian.
