Which early comedic actor lost the thumb and index finger of his right hand when he mistook a bomb for a prop?

Bad idea bringing a real bomb to a studio...

He was a brilliant performer, doing all his own stunts

Hiqq, I do agree!! it reminds me of that kid, cant think of his name. I think he was Bruce Lee's son. he had a gun and it was a prop, I think!! ended up getting shot by him or someone else and he died. Do you remember the story? My facts could be wrong but, only his father might be wrong, all the else is true!!
