Dorian Gray is the secondary antagonist in the 2003 film The League of Extraordinary Gentlemen.
He is portrayed by Stuart Townsend.
Dorian is a very smug man who cannot be injured and doesn't even age, due to a cursed portrait of himself that ages each year instead of him. However, to gaze upon the portrait would strip him of his immortal powers. Originally a member of the League as recruited by M (who is actually the terrorist known as Fantom) and the former lover of team member Mina Harker, Dorian is later revealed to be a double agent working for the Fantom in order to instigate the Fantom's plans for a world war.
To that end, Dorian secretly stole many of the League's powers, such as taking pictures of the inner workings of Captain Nemo's submarine The Nautlius, stealing a vial of the Hyde formula from Dr. Jekyll, cutting a skin from the invisible thief Rodney Skinner, and obtaining vampire blood from Mina by causing a drinking accident. It also turns out that Dorian involved of the Fantom's intention of using Allan Quartermain to capture Hyde in order to obtain the Hyde fomrula. With the elements in his hand, Dorian escapes in an escape pod to the Fantom's fortress in the Asiatic Arctic, unaware that Rodney has stowed away in the pod and secretly giving directions to the League.
When the League locate the Fantom's fortress in the Asiatic Arctic, Mina confronts Dorian and, after fighting him, finally defeats him by forcing him to look at his magical portrait. Dorian screams in terror as the portrait reverts back to its original form and Dorian begins rapidly aging instead, before disintegrating into dust.
