Question: Which actor in the lead roles of Law & Order SVU is the oldest? Passage:For the lead roles, Christopher Meloni was cast as Detective Elliot Stabler and Mariska Hargitay was cast as Detective Olivia Benson after they auditioned together. Hargitay, who had to move from Los Angeles to New York when she got the role, said she was able to do this on short notice because she was already planning on moving to New York to pursue a Broadway career. The squad commander role was filled by Dann Florek, who had portrayed Captain Don Cragen for the first three seasons on the original Law & Order and later reprised his role in . He joined the cast on the condition that he not be asked to audition. Richard Belzer was cast as Detective John Munch, continuing his role from the series . In Belzer's words, he was cast because "Dick Wolf and Tom Fontana got drunk at a party". Halfway through the season, Richard Belzer reprised his role of Munch in , which briefly shows his character out on a case in his SVU context in New York. At Belzer's insistence, his character was partnered with Brian Cassidy, who was portrayed by Dean Winters. However, Winters' contractual obligation to the HBO series Oz forced him to leave halfway through the season. Michelle Hurd, who portrayed Detective Monique Jeffries, filled Winters' void for the remainder of the season, and was at that point added to the main credits.
