The thread is asking about characters who are a combination of live-action and animation, not movies which feature both, 'cause there are plenty of those: Mary Poppins, Bedknobs & Broomsticks, The Phantom Tollbooth and Twice Upon a Time, to name only a few. Judge Doom from Roger Rabbit and Holly Wood from Cool World would be examples. Stanley Ipkiss's alter ego in The Mask would be another.
