The most widely-known version of the character is probably that of the 1994 film adaptation The Mask starring Jim Carrey, but the character is much darker in the comics than that movie or the subsequent animated series let on. Initially inspired by Joker, the character first appeared in 1987's Dark Horse Presents #10 as Masque. Created by Mike Richardson and Mark Badger, the character was later revamped by artist Chris Warner and soon began appearing in the Mayhem anthology series. A number of limited series by John Arcudi and Doug Mahnke followed and cemented his cult following.
The comic was much more violent than most fans of the film would expect. The character of Stanley Ipkiss, known to the public as Big Head when he's wearing the magical mask, took brutal revenge against his enemies using the abilities of the mask, whereas the film version's exploits were much more comedic and PG-rated. Fans have been hoping to see another adaptation of The Mask that adheres closer to the source material than the Carrey film did, and Monaghan could be the actor to make that happen. However, it's not clear at this time if there are any plans to make another adaptation of The Mask.
Monaghan has played two roles on Gotham so far: Jerome and Jeremiah Valeska. Although those twin brothers are definitely proto-forms of Joker, he's set to play a third character before the series end, which most speculate is a more fleshed out version of the Clown Prince of Crime.
