Randy Quaid: "It's the gift that keeps on givin', Ang..."

Hell hath no fury like Randy Quaid scorned:

The lawsuit, filed Thursday in Los Angeles, accuses the filmmakers of getting Quaid to cut his seven-figure asking price by portraying Brokeback Mountain as a "low-budget, art-house movie with no prospect of making money." Only later, it says, did Quaid learn Brokeback was a Hollywood-backed production with a budget worth "millions more" than he'd been told.

Quaid, the lawsuit alleges, was hoodwinked:

"Defendants took advantage of Randy Quaid's devotion to filmmaking as an art form and his support of 'true' art films to obtain his performance in Brokeback Mountain," the lawsuit says.

The lawsuit's biggest eye-opeener: who knew that Randy Quaid commands a seven-figure price tag?
