Which Heavyweight Is This ?

Lou Nova and his "cosmic punch "

 

Looks like Patrick Comiskey to me.
He was in movies too.

 

Or Pat Comiskey, a coming heavyweight champion until Max Baer burst his bubble with one right hand !

 

He was in "The Harder They Fall", played the 'Ernie Schaaf' character who went in the ring damaged and got like by the 'Carnera' character.

 

Unforgiven sounds sure, i guess its Pat?

 

Just had a look at "The harder they fall" and he looks like Comiskey, but he is not credited in the cast.

 

True.
I hate it when old movies didn't credit every actor. He even had a few lines if I remember rightly.
Anyway it's him. I just checked imdb.
