I’ve just heard that John Coates, best known for being the “production supervisor” on Yellow Submarine, a co-producer of Heavy Metal, and producer of several notable shorts (The Snowman), series (The World Of Peter Rabbit) and features (When The Wind Blows) has passed away at age 84.

Coates co-founded TVC London (aka TV Cartoons Ltd.) with George Dunning in 1957 and was known as the business partner of the duo. In the 1960s, TVC produced the original Beatles TV cartoons and the Cool McCool series for King Features – and that led to them being the studio behind Yellow Submarine (1968). Coates continued to align himself with quality work throughout the years, and was most recently nominated for an Academy Award for Joanna Quinn’s short Famous Fred in 1997. A legend of the British animation industry, John Libbey published a biography of Coates last year.
