Double Bill (1969)

"The Compartment and Playmates by Johnny Speight"

In the first part, The Compartment, an insane man boards a quiet railway coach and starts to annoy a patient man trying to read a paper with incessant small talk in an increasingly menacing manner until he finally pulls out a gun and screaming class hatred bile, humiliates the man until his stop is reached. In part two, Playmates, he breaks into a lonely house and proceeds to terrorise a spinster woman who lives there.
