Wesley Mann

Wesley Mann (born September 6, 1963) is an American character actor, best known for his role as the caterpillar on Adventures in Wonderland and for playing the spluttering teacher-turned-principal Mr. Lawler on That's So Raven.

Many of Mann's roles are minor and he frequently delivers only a handful of lines, but he has a somewhat distinctive appearance, that of a long-suffering, vaguely glib demeanor that makes him easily recognizable whenever he shows up in a film or on television. He is, by definition, a character actor, and thus he has never performed a lead role.
