The Star Wars actress recently ended her run on the New York stage in her one-woman show Wishful Drinking, which is based on her book of the same name about her early struggles in Hollywood.
But Fisher has now become entangled in an ugly dispute with her producer, Jonathan Reinis, who she claims owes her $60,000 (£37,500) for her time in the show. She also alleges he failed to keep a promise to move the production from the non-profit Studio 54 theatre, which is owned by the Roundabout Theater Company, to a "first-class Broadway house" at the end of last year (09).
In an email to New York Post columnist Michael Riedel, Fisher writes, "As you can imagine, Jonny seems to be a bit cranky, which I figure is why he still hasn't paid me the remaining money he owes me. For whatever reason, (he) was unable to get (the move) done. I don't know why, since I was told there was plenty of theatre availability. So, his rights reverted back to me under our contract.
"Trust me, there are a lot of things in the contract I wasn't thrilled about. But I fulfilled my obligations, didn't miss one show and made a lot of money for my producer - from which I'm assuming he ultimately plans on making a donation to the Roundabout Theater Company. This isn't the first time I've had to force Jonny to fulfil his obligations under our deal. I hope he'll comply in this circumstance soon. This whole thing doesn't have to get ugly."
Reinis' attorney, Ronald Feiner, has responded to Fisher's claims, contending the Studio 54 theatre is a "first-class" Broadway house because shows performed there are eligible for Tony awards.
Feiner also insists Fisher should be grateful to Reinis for the play's success and alleges the actress is the one who hampered the production, by failing to agree to a tour.
He adds, "(My client) should not be dismissed by Carrie Fisher in this way. He took her show from nothing - it had no sets, no video, it had nothing - and turned it into a hit.
"It is our belief that she owes us a substantial amount in lost profits from what could be a lucrative tour. We have offers from Australia, Canada and theatres around the United States, but we are unable to close the deal because she will not perform the show."
