Brittany Murphy's career is in a downward spiral!

The once promising young actress has not starred in a hit film since 2005's Sin City, a movie in which she was just a featured player.

Murphy has never been the lead in a box office success, and these days, industry insiders comment more on her erratic behavior and crazy husband than her career (or lack of one).

Adding insult to injury, Disney has just axed Brittany from their deal with them!

Back in 2006, the Mouse House announced that Murphy would be their new voice of Tinkerbell. They planned to use her for work on new Tink DVDs and much more.

Well, this past week, Disney revealed that Brittany was out and there would be a new voice for Tinkerbell, actress Mae Whitman.

No explanation was given for Murphy's "departure" - but, really, we don't need one!
