Will's oldest brother Sam, originally played by John Slattery, was replaced by Steven Weber for the role of Sam.
Sam (Steven Weber) states that the ride felt like "five hundred twenty-five thousand, six hundred miles". This is a reference to the song "Seasons of Love" from the Broadway musical "Rent" that contains the line "Five hundred twenty-five thousand, six hundred minutes", which is the number of minutes in a common year.
This is Marilyn Truman's first appearance since the season 7 episode "From Queer to Eternity".
Marilyn's unusually-shaped compact camera, which she accidentally holds facing the wrong way when taking photos of Jordy, is an Olympus Stylus Verve-series model, also known in some markets as the µ Mini Digital.
Jack plays the keyboard for Jordy's performance. In real life Sean Hayes is classically-trained pianist and is very talented.
