Mickey Knox seems to have blackisted himself.


Mickey Knox (Born Abraham Bullistein) Claimed he was blacklisted during the McCarthy era and was forced to move to Paris and Rome to work. But there is something not right about his story.
Knox, who at best was a bit part player and extra, claimed that he was blacklisted because he signed a petition called “The Thomas Rankin Committee Must Go” and that he had attended the Actor’s Lab, a Communist front. He said that his signature on a friends of the court document to the US Supreme Court to hear the case against John Howard Lawson and Dalton Trumbo, who were writers with the Hollywood Ten, is the true reason his career was blacklisted. But more than a thousand actors signed the Rankin petition and several hundred actors  signed the Supreme Court petition and they weren’t blacklisted.  
Knox said that he learned he was blacklisted in 1956. He made his last appearance in the US in the fall of 1957, so it’s safe to assume he left the US  later that year. He returned to the US  from Europe on January 23, 1959, meaning he was “exiled” as he put it, for two years.
It seems that Knox couldn’t cut it as an actor, producer or writer in Hollywood (He would do all of those things later in his career)  and he “fled” to Europe claiming to be a blacklisted actor.
Knox made six film in 1949 and was uncredited in one of them and fewer than 3 lines in the others. He made one film in 1948, a bit part and two in 1947
