Canned Heat is the first of two S4C commissions for Blunt Pictures, a division of Siriol Pictures set up to produce adult animation. It is described by the producers as "a humorous exploration of prejudice and intolerance featuring animated cans of soup which prove that despite our differences, we all end up in society's melting pot". Directed, written and animated by David Sethi, the four-minute film uses a mixture of model animation and live action. It is produced by Robin Lyons and features the voice of comedian Al Murray. Blunt's second commission is The Three Lancers about Iraqi soldiers looking for WMD.
