The use of Dorian Tyrell in the Jim Carrey movie The Mask was actually fairly understandable. In the comic books, the Mask really doesn't have a very recognisable or defined enemies - and the few antagonists he does have really don't cut it. Take Walter for example. In the comic books, Walter is a hulking mute man - but the fact is that he is merely a man. How can he truly be portrayed as a threat to a man who is essentially a living cartoon? Tyrell was created with the intention of giving Stanley Ipkiss a contrasting villain - someone who wants the Mask for all the wrong reasons and who becomes a monster when he wears it, and that's exactly what he was. The movie was both a critical and commercial success and the main antagonist has to be given some credit for that.
