Peter Lorre
In the 1995 cartoon short "Carrotblanca", a parody/homage to "Casablanca", Tweety appeared as "Usmarte", a parody of the character Ugarte played by Peter Lorre in the original film. In several sequences, Tweety was speaking and laughing in character like Peter Lorre. He also does the Looney Tunes ending instead of Porky Pig or Bugs Bunny. This is also notable for being a rare instance where Tweety plays a villain character.
