Lawrence's pock-marked complexion, brooding appearance and New York street-guy accent made him a natural for heavies, and he played scores of gangsters and mob bosses over the next six decades. Later, Lawrence found himself under scrutiny for his political leanings. When called before the House Un-American Activities Committee, he admitted he had once been a member of the Communist Party. He named Sterling Hayden, Lionel Stander, Anne Revere, Larry Parks, Karen Morley and Jeff Corey as Communists. He was blacklisted and departed for Europe, where he continued to make films.
