Cult cartoon series The Simpsons is at risk of being axed from television because of a pay dispute with actors who work on the show.

Dan Castellaneta, Julia Kavner and Nancy Cartwright who provide the voices of Homer, Marge and Bart Simpson have been told they face a 45 per cent pay reduction.

Reports claim they already earn an estimated $8millon per year – but if the row escalates it could mean the end of the hit show in Spring 2012.

Fox Television has apparently already turned down a revised offer of a 30 per cent cut with a share of profits, The Daily Beast reported.

The Simpsons, which is now in its 23rd season, has been a global hit - being turned into Hollywood films and creating a huge merchandise industry.

In statement, 20th Century Fox TV said: “The Simpsons is as creatively vibrant as ever and beloved by millions around the world.

“We believe this brilliant series can and should continue, but we cannot produce future seasons under its current financial model.

"We are hopeful that we can reach an agreement with the voice cast that allows The Simpsons to go on entertaining audiences with original episodes for many years to come."

Bart Simpson and his dysfunctional family worked their way into everyday life after first appearing on the Tracey Ullman Show way back in 1987.
