Deliberate mistake: In the fire scene, Jon tries to catch Garfield from the chandelier at the main staircase. When Jon reaches out to grab Garfield, there is no rail on the stairs. It comes back in the very next shot & disappears again after Garfield says "Need a lift?"
Garfield Gets Real (2007)
1 deliberate mistake
Directed by: Mark A.Z. Dippe, Kyung Ho Lee
Starring: Frank Welker, Gregg Berger, Jennifer Darling, Rajia Baroudi
Other mistake: In the fire scene, after Garfield says "Need a lift?" You can see Wally in the corner smiling. But he's in a fire. He wouldn't have been smiling in a dangerous situation. Probably an animation screw-up.
