Director Kevin Smith doesn't mind if critics insult him when he appears in movies - just as long as they are funny. The Clerks director was slated by some critics for his small part in the new Die Hard movie but admits it doesn't bother him because the comments make him laugh. Smith was branded "increasingly, an indie-cred Muppet for studio movies" by a Boston based critic after appearing in the Bruce Willis picture. But the film maker responded to the taunt in good humour, positing a message on his website saying: "Any outrage I might've mustered evaporated after reading 'indie-cred Muppet' - unfair or not, that's funny."
