Actor Randy Quaid has reportedly taken legal action against the producers of Brokeback Mountain, saying he was duped into accepting less money for his work.
Quaid claims he was told the film had no chance of making money
He alleges Focus Features persuaded him to defer his normal pay by misrepresenting the project as a low-budget film, according to Variety.
Producers James Schamus and David Linde retained his services on "economically unfavourable" terms, he has claimed.
Quaid, 55, is suing for $10m (£5.7m). A Focus spokeswoman declined to comment.
"Randy Quaid is an instantly recognisable household name and much-admired actor on the world's stage with a worldwide box office total of nearly $2 billion (£1.1bn)," reads the legal action filed at Los Angeles Superior Court on Thursday.
"Defendants were engaging in a 'movie laundering' scheme designed to obtain the services of talent... for a picture that, in reality, had studio backing and would be exploited using traditional studio marketing and distribution techniques."
Brokeback Mountain won three Academy Awards in March and has made nearly $160m (£92m) worldwide, according to trade newspaper Variety.
Quaid's action - which also names Del Mar Productions as a defendant - does not state what he was actually paid for playing the role of ranch manager Joe Aguirre.
The actor's other films include Kingpin, Independence Day and Not Another Teen Movie.
