The Old Grey Hare (1944)

Continuity mistake: When Elmer Fudd picks up the newspaper beside him, you can see that he is holding the paper with his hands whilst looking at the front page, but when we see the newspaper in the next shot, his hands are nowhere to be seen.

Revealing mistake: When Bugs Bunny is walking away from Elmer Fudd, you can see a futuristic building in the background that keeps disappearing repeatedly when it reaches the end of the frame.

Continuity mistake: When Bugs Bunny is shot by Elmer Fudd, he collapses to the ground and you can see there is a green bush beside him, but when we see Bugs in the next shot, the bush has disappeared.

Trivia: When Elmer finds himself in the year 2000, he picks up a newspaper with a headline saying "Smellevision replaces Television!" Underneath this there is a caption saying "Carl Stalling sez, "It will never work!" Carl Stalling was the music composer and arranger for the Looney Tunes and Merrie Melodies shorts produced by Warner Brothers.

Trivia: When Bugs Bunny gives Elmer Fudd a stick of dynamite at the end of the cartoon, the dynamite explodes after the fade-out, shaking the "That's All Folks!" title card.

Bugs Bunny: You ain't got me yet, by Gum! He he he he! Ow, darn this lumbago.

Bugs Bunny: So long, Methuselah.
