First of all I don't think it is necessary to start a panic over this just yet but according to various sources (Variety, Hollywood Reporter, and IGN) Fox is auditioning for new voice actors auditioning new actors for the roles of our favorite Futurama characters after failing to reach an agreement with the original voice cast.
While it is indeed very important that the show goes on, I secretly hope that Fox won't slash the budget for voice actors because a very big part of the success of Futurama lies in its excellent cast.
"We love the 'Futurama' voice performers and absolutely wanted to use them, but unfortunately, we could not meet their salary demands," the studio said in a statement Friday. "While replacing these talented actors will be difficult, the show must go on."
PS: I'm sure it can't hurt signing some petitions on this subject.
