Hollywood filmmaker Kevin Smith sparked rumours of a feud with Bruce Willis by reportedly launching into a rant about the actor after he failed to show at an event for their new film A Couple of Dicks.

The action star was noticeably absent at a recent wrap party in New York, reports the National Enquirer.

According to the publication, the pair has been at odds over Willis' demands to add his own creative input to the film - and Smith took advantage of his star's absence to criticize him in a scathing toast.

Smith is said to have cheered, "I want to thank everyone who worked on he film, except for Bruce Willis... who is a f--king d--k!"

A spokesperson for Willis had not responded to requests for comment as WENN went to press.
