But last month, he filed suit on behalf of four Californians who allege that Fox Broadcasting Co. stole their idea behind the hit reality television show, "So You Think You Can Dance." During a 2003 meeting, his clients told an agency executive about their concept and agreed to write, direct and produce the contestant show if it were accepted. No script changed hands, and nothing was copyrighted. But in a suit filed under six California laws, Terrell said that his clients should be compensated for their idea because they had a contract. The case represents a new type of entertainment lawsuit for his firm, Los Angeles-based Engstrom, Lipscomb & Lack, he said. Cassese v. Martin Erlichman Associates Inc., No. BC353893 (Los Angeles Co., Calif., Super. Ct.). "This case came to us as something new and different," Terrell said.
