Law & Order (season 18)
The 18th season of Law & Order premiered on NBC on January 2, 2008, and concluded on May 21, 2008.
Production
On May 13, 2007, NBC renewed Law & Order for an 18th season of 22 episodes as part of a deal made by series creator Dick Wolf and NBC. Though the series was originally scheduled to air on Sundays as a midseason replacement for NBC Sunday Night Football,TV Guide reported on December 4, 2007, that Law & Order would debut instead on Wednesday, January 2, 2008.
René Balcer, who had developed and produced spinoff Law & Order: Criminal Intent, returned to Law & Order this season as executive producer.
Cast and crew changes
In May 2007, cast member Fred Thompson (Arthur Branch) departed the series to focus on his political career, having already been considered an unofficial candidate for the 2008 presidential election. His place on the series was filled by cast member Sam Waterston (Jack McCoy), whose character would be promoted to fill the position vacated by Branch's character. In turn, Linus Roache was added to the cast as EADA Michael Cutter, who replaced the position that Waterston's character would vacate. Because of the equal-time rule, which requires that broadcasters treat legally qualified political candidates equally in regard to air time, NBC announced in July 2007 that it would not broadcast any episode of Law & Order in which Thompson appeared after September 1. However, Thompson did not officially declare his intention to seek nomination until September 5, 2007, when he appeared on The Tonight Show with Jay Leno.
