In the Wee Small Hours was originally presented as a two-hour telemovie, however, it has been subsequently divided to air as two one-hour episodes. The two episodes are titled: "In the Wee Small Hours Part I" and "In the Wee Small Hours Part II".

"In the Wee Small Hours" is the first and so far only time all four detectives (Goren & Eames, Logan & Barek) are featured in the same episode. It is also the first instance shown of the two sets of partners working together.
