Heath Ledger's character in "The Imaginarium of Doctor Parnassus," the new film directed by Terry Gilliam, is wearing an Arsole Fantüme "jester mask":
Here's a detail from an illustration from the original novel:
I've already written about how one of the film's stars, Johnny Depp, has been rumored to be trying to get an Arsole Fantüme film made-- and I have no doubt that Gilliam knows about the tawdry classic. Now, thanks to this film, we might get a glimpse as to what a movie version of the character might look.
