Dwight Iliff Frye (February 22, 1899 November 7, 1943) was an American actor remembered mostly for his appearances in the classic Universal Horror films Dracula (1931), Frankenstein (1931), and Bride of Frankenstein (1935), in which he codified both The Igor and The Renfield.
Frye had an extensive and varied stage career (including a part in the first American production of Six Characters in Search of an Author), gaining some positive attention for his roles on Broadway, but his hot eyes and earnest delivery were a bit overpowering on film in addition to his short stature. Hollywood cast him mostly as pathetic nutcases, but he kept trying to pursue a successful film career, and accepted any role he could to pay his bills. Frye's other roles were usually limited to very small, but memorable parts on B-list gangster movies (including the original 1931 version of The Maltese Falcon), usually as the villain's henchman. He appeared in short film Don't Talk as a saboteur at a war munitions plant.
A devout Christian Scientist, Frye refused to seek medical attention for his secret coronary condition, and his untimely death by heart attack came just days before he was supposed to begin filming a prominent "straight" role, as Woodrow Wilson's Secretary of War in Wilson. Whether or not that film could have finally launched him into stardom is up for debate.
