He was a victim of the Hollywood blacklist during the HUAC
hearings. Although he had already been signed, 20th Century-Fox wanted
to remove him from The Day the Earth Stood Still (1951).
Producer Julian Blaustein felt that Jaffe was so crucial for the
role of the Albert Einstein-like Prof. Barnhardt that he
appealed to studio chief Darryl F. Zanuck. Zanuck approved Jaffe
for the role, but it was his last Hollywood film until the late 1950s.
