Young Frankenstein
Daisy's story is below the poster.

Daisy's role was the castle's house cat, so she shared many scenes with Cloris Leachman. That was fun because Leachman was a master of comedic timing and improvisation. Daisy had typically played quiet, laid back cats in her previous films, so she enjoyed the opportunity to arch her back and hiss at the horses when she was with Leachman or whenever anyone else uttered "Blücher."
The hardest scenes to shoot were with Gene Wilder in the castle. Even though he and Brooks were the writers, he would break character and laugh at the jokes and sight gags, causing the scenes to be reshot and reshot. T
he scene where Madeline Kahn arrives at the castle had to be shot 15 times before Wilder could keep a straight face and make it through the scene. That was typical of most of the scenes throughout the filming. That really annoyed Leachman, Teri Garr, and Daisy who felt their best scenes were scrapped because of him.
Mel Brooks usually appeared in his own films, but he was not onscreen in this one. However, he made off-camera "appearances" as the sound of the howling wolf, the voice of Frederick's grandfather, and the sound of the shrieking cat.
Daisy would have naturally done a much better shrieking cat sound if the opportunity had arisen. But when Gene Wilder threw his dart off camera, Mel Brooks suddenly ad-libbed a cat-like shriek to create the illusion, and he kept that in the film. Daisy was disappointed.
