Personal Quote:

The greatest thing that ever happened to me in terms of my acting was the audition for To Live and Die in L.A. (1985). After I read, William Friedkin put down the script and said, "You got the part". I really thought it was a joke. I went back to my hotel room and took a bath and they called and wanted to make a deal. I still didn't believe it. See more »
