Jack Black is scared he is going to end up facing George Lucas in court - after writing a song about Star Wars'.
The actor is currently working on his band Tenacious D's new album - and the first song is titled 'Death Star', a feature of Lucas' sci-fi series.
Lucas is famously protective of the movies - and Black is waiting for the lawsuit to arrive.
He says: "We have a new song called Death Star and hopefully George Lucas will not sue us. We just need about 13 more songs to go with Death Star so I'm thinking the CD is gonna come out in the tens, 2010."
