I believe it has been mentioned here that Nick Park would retire Wallace & Gromit due to the passing of Peter Sallis. I had the thought the other morning that a Last of the Summer Wine revisited in the style of Wallace & Gromit would be great.
A clay-mation type animation appeals to me more than a traditional two dimensional Simpsons cartoon style. Nick is highly skilled in capturing the nuanced facial expressions via clay, more so than is possible with a cartoon style rendering. Imagine the stare from his evil penguin character could match the powerful eyeballs of Foggy or Howard trying to hypnotize someone. The cast from First of the Summer Wine could do the voice overs.
