At first, I wondered if Stahl might have gotten a head start in the business by virtue of being related to the auteur director, John M. Stahl, who died in 1950. That Stahl made The Keys to the Kingdom and Leave Her to Heaven. Auteur theory expert Andrew Sarris noted that John M. Stahl made Douglas Sirk movies before Sirk practically invented the genre of intelligent, cinematically remarkable soaps, including at least one Rock Hudson vehicle (Magnificent Obsession) and the classic weeper, Imitation of Life, with Lana Turner, both of them remakes of even more sentimental Stahl films. However, nothing in Nick's bio indicated any relation to John M. Stahl.
Nick has had some serendipitous career breaks. For example, he did one of the Terminators with Arnold Schwartzenegger. He also had a short-lived cable series about the strange world of carnies, Carnevale. He had a role in The Thin Red Line and worked with Larry Clark in Bully. Unfortunately, he's lately been more discussed more often because of his strange disappearances, reputed use of drugs, and post-marital problems. This is unfortunate and sad. His fans hope it's a passing phase and that he will make many more movies. I know I do.
