Saturday Evening Puss (1950)

The popular cartoon cat and mouse are thrown into a feature film. The story has the twosome trying to help an orphan girl who is being berated and exploited by a greedy guardian.

Professor Jerry teaches a course in how to outwit cats, but his pupil seems to know more than Jerry.

A moment after a bottle of white shoe polish pours on Jerry, Tom hears on the radio that a white mouse, having swallowed an explosive, has escaped from an experimental laboratory and that slightest jar of the mouse could cause it to explode and blow up the entire city. It is then that Tom notices now-white Jerry and concludes it's the escapee.

Tom's new book on "how to catch a mouse" doesn't prove too helpful against Jerry; actually, Jerry seems to make better use of it than Tom.

Tom Cat is a concert pianist who plays beautifully until he is interrupted by Jerry Mouse.

Jerry crashes a vase onto Tom's head, which gets Mammy to throw Tom out. Jerry at first revels in his freedom, but soon tires of this, and, under a flag of truce, hatches a plan with Tom.

Jasper is given an ultimatum by his master: break one more thing and you're out. Rodent Jerry does his best to make sure that his tormentor "gets the boot".

Jerry and his diapered little mouse friend flood the kitchen, then use the freezer to turn it into a skating rink. Even though Tom finds a pair of ice skates, the mice have no problem outmaneuvering him.

Tom, complete with mortarboard, is teaching a kitten the basics: "cats chase mice." But Jerry keeps subverting this lesson at every opportunity.

At the home of Viennese composer Johann Strauss lived Johann Mouse. Whenever the composer played his waltzes, the mouse would dance to the music, unable to control himself. One day, when Strauss was away, the house cat played his master's music. When word got out about a piano-playing cat and a dancing mouse, they were commanded to perform for the emperor.
