It was originally planned that Postlethwaite would have a larger role, but when director Nick Hamm saw how ill he was, he wrote him "a new role that allowed them to film around [his] physical needs and abilities... a very funny, ridiculous part".

Hamm later commented: "It was very apparent when I saw him at that moment that there was no way that this guy was ever going to go on screen or stage again."
