From the Drain (1967)

This black and white short (roughly 13 mins) is simply brilliant, in my humble opinion. Shot in a darkened bathroom, it concerns a surreal dialogue between two very strange men sitting in a bath (that probably counts as a spoiler for this film). One man is camp and talkative, while the other is a nervous nutter, concerned that a bathplug be placed in the 'drain end of the tub' to stop 'tendrils' from 'coming up from the drain'.
