A National Film Board public service film detailing the steps to collect and process blood serum donations for transport to Britain during WWII. Interesting for the differences and similarities to modern processes.
Serials usually spawned feature film versions, but with this film, it was the other way around.

Bugs Bunny heckles a black hunter and escapes from a bear. One of the “Censored 11” banned from TV syndication by United Artists in 1968 for racist stereotyping.
