If you saw the latest Wallace and Gromit over Christmas you most probably enjoyed it like we did. You might not have realised that the creators, Aardman, needed a busy legal team to make it.

Why? You wouldn’t think a show so innocent would need legal, but it turns out every single one of the many, many brilliant puns has to go past the lawyers.

Director Merlin Crossingham told Cartoon Bew: “Back in the day, no one ever checked those things from the legal department. Now everything we have to check. The laws of parody have changed in entertainment, and the litigious side of our society has moved on a peg”.

Imagine being those lawyers.
