Richard Belzer originally asked Dick Wolf if Munch could join Law & Order (1990) as Lennie Briscoe's new partner. But Jesse L. Martin had already been cast.

Winters was still under contract with Oz (1997), and had to leave the show after the first thirteen episodes. Winters returned as a recurring cast member in the fourteenth season.
Christopher Meloni was starring on Oz (1997) simultaneously with this series. He eventually left "Oz" because he felt that he could no longer do both shows at the same time. But Meloni missed "Oz", and decided to return the next season. He decided that being able to work on two great shows simultaneously was worth the physical and emotional toll.

At the start of season thirteen, episode titles were no longer one word. Season thirteen is also the first season without Detective Elliot Stabler (Christopher Meloni).
