Hi Robbie and Bill,
this taken from the IMDb Biography on Brad Dexter,
as you can see it amounts to not very much!!
He was so totally eclipsed by the others.
I think his main claim to fame was that he was a buddy of Frank Sinatra's. They finally had a falling out - this is if my memory serves - when he had a chance to direct a movie Sinatra was in and they did not see eye-to-eye!
Cheers - Jay
