Mariska Hargitay's character has very short hair in the first 2 episodes of this season (commented on by Richard Belzer's character Munch). Her hair is now inexplicably shoulder length in this episode. Therefore, it can be assumed that this episode was most likely filmed shortly after season eight finished production.
Dann Florek, who plays Captain Cragen, guest starred on Melissa Joan Hart's previous television show Sabrina the Teenage Witch (1996) in the episode Cat Showdown (1997), which had aired a decade earlier before this episode aired.
Melissa Joan Hart also originally worked with Mariska Hargitay in the movie Love American Style (1999) back in 1999.
Diane Neal and guest star Melissa Joan Hart go on to play sisters in the movie My Fake Fiancé (2009).
