Corrected entry: In the scene where Eddie Valiant follows Jessica into Toontown, he crashes the 1939 Plymouth Coupe he is driving into the back of her parked Packard at 1:10:40. The hood (including the top of the grill shell and hood ornament) on the Plymouth is forced opened from the front by the crash (like the hood opens on a modern car). A 1939 Plymouth has a butterfly style hood that opens from the sides and the grill shell and ornament do not raise with the hood. Example: http://willoughbycoach.com/1939%20Plymouth%20Coupe.jpg Later, there is also no damage to the grill shell and ornament when Roger is leaving Toontown 1:17:42. For the hood to open like it did in the crash, those pieces would have to have been torn from the grill. (01:10:40 - 01:17:40)
Corrected entry: When Eddy toasts to Earl's dismissal, he says, "Cheers to the pencil pushers. May they all die of lead poisoning." Until the 17th century (until graphite was found and first used for writing) the archetypal 'pencils' were indeed made of lead alloys, and even today, due to its color, the graphite is sometimes referred to as 'lead'.
Corrected entry: When Roger bursts through Maroon's window blind, he leaves behind a clean outline of his body shape in it, However look at the section of blind between his legs in the outline. They are magically floating in mid-air as they are not attached to the blind's drawstrings either side.
Corrected entry: When Valiant grabs Roger after he is singing, dancing and smashing plates on his head, if you look carefully you can see that Roger is a frozen-stiff cardboard cut-out. This was to hide the machinery that was smashing the plates.
Corrected entry: When Eddie defeats the judge by hitting the dip valve with the extended boxing glove, the judge is shown being pushed forward by the spray, however when the camera cuts it shows Eddie sitting there with the spray going past him but the judge mysteriously vanishes.
Corrected entry: In the scene where Roger is looking at the photos of Jessica and Acme playing patty cake, Roger flips through the pictures fast enough that it looks as though Valiant had just kept clicking the button on the camera. This isn't possible because when Valiant was taking the pictures, he had to wind the camera after every shot.
Corrected entry: We are repeatedly told that toons don't feel pain, yet in one scene, Yosemite Sam emerges from a bar with his butt on fire, yelling in pain.
Corrected entry: In the scene where Eddie Valiant is in R.K. Maroon's office not far from the beginning of the film and Maroon writes him out a cheque to take pictures of Jessica, Maroon mentions Dumbo working for peanuts and Valiant says, "well I don't work for peanuts, where's the other $50?", however you don't see Valiant actually look at the cheque to see that he's only been paid $50.
Corrected entry: The movie takes place in 1947. The Christopher Lloyd character has a plan to take out Toon Town in order for him to acquire the land, which happens to be in the path of a planned freeway to Pasadena. Construction on the Arroyo Seco Parkway (US Route 66) between downtown Los Angeles and Pasadena began in 1939 and was opened to traffic December 30, 1940. It was renamed the Pasadena Freeway in 1955 and, aside from some cosmetic changes, remains basically the same to this day.
Corrected entry: At the very end of the film, the Roadrunner and Wile E. Coyote appear in the "roll call" with all the other characters. While the film takes place in 1947, the first Roadrunner and Coyote cartoon actually appeared in 1949. The filmmakers were aware of this, but Steven Speilberg, a huge fan of the characters, insisted on it anyway.
Corrected entry: The film takes place in the year 1947. Near the end, when Benny is examining the remains of Doom, he says that he's been a cab for thirty-seven years. American Taxi cabs didn't look anything like that back in 1910.
