Stupor Duck (1956)

Continuity mistake: When Cluck Trent is using his typewriter at the beginning of the short, you can see there is nothing by the machine, but when the camera closes in on Trent, a sign saying "Cluck Trent Reporter" appears.

Continuity mistake: When Cluck Trent is telling us about Aardvark Ratnik, he is holding a paper cup in his left hand. When he says "This looks like a job for Stupor Duck!" we cut back to Trent, and the paper cup has disappeared.

Continuity mistake: When Cluck Trent leaves his office to change into Stupor Duck, the floor is completed covered in water. But when Stupor Duck enters the editor's office, look behind him and you can see the water has gone.

Trivia: When Cluck Trent (Daffy) takes a break from writing, he pulls out from his pocket a box of "Dr. Pierce's Mild Pills" - a reference to the Warner Brothers story writer, Tedd Pierce.

Trivia: When the narrator tells the audience that Stupor Duck is able to "jump the world's tallest buildings", we see Stupor Duck near a building with a window labelled "McKimson Associates" - a reference to the Warner Brothers director, Robert McKimson.

Trivia: In the opening sequence, the announcer says that Stupor Duck is "more powerful than a steaming locomotive" and we see a barely functional train. What you actually see is a clip from the 1945 Warner Brothers cartoon, "Hare Trigger."
