Batman

In the opening credits of this episode and the second and in the closing credits of this episode the Special guest Villain was billed as ??? as Falseface. It was only in the ending credits of the second episode that Malachi Thorne was credited.

False-Face was a substitute version of Two-Face, who first appeared in Detective Comics #66 (August 1942) and was patterned by both Batman creator Bob Kane and Batman uncredited co-creator Bill Finger after the 1931 horror film Dr Jekyll and Mr Hyde starring Fredric March. Two-Face's original name was Harvey Kent but was changed to Harvey Dent to stop confusion with Clark Kent (i.e. Superman). Two-Face wouldn't be back until the early 1970s in part due to the 1954 book written by Dr. Fredric Wertham entitled Seduction of the Innocent. Wertham also thought that Batman and Robin were homosexuals. Probably because of his own homophobia, he decided to take it out on The Caped Crusaders, but there was no proof of Wertham's accusation. The Comics Code Authority (starting in 1954), though no longer strictly enforced, is a legacy of Wertham's crusade.

Billy Curtis, one of the most famous "little people" in Hollywood, is best known as The Mayor Of Munchkinland in the MGM 1939 classic movie The Wizard Of Oz.

Although Finger's original creation hasn't reappeared in recent times, the animated Batman Beyond series revived the idea of a villain named Falseface for an episode called Plague. Malachi Throne did not voice the character but another character, Fingers, in 11 episodes later called Speak No Evil.

Malachi Throne's real face is briefly seen when he is "disguised" as the armored car guard, although he's wearing a presumably fake mustache.

The late Bill Finger created False Face in Batman #113 (February 1958); this episode was based on a June 1958 comic book story featuring The Protean Plunderer.

Gary Owens later became the comical ear-cupped announcer for Rowan And Martin's Laugh-In which ran on NBC from 1968-73. He would later provide the 1950's Batman voice on the October 10, 1998 episode Legends of the Dark Knight in the Batman Gotham Knights animated cartoon.
