Paul Shaffer, David Johansen and Bill Murray have worked together in another Christmas movie, Scrooged (1988), although Shaffer was only onscreen for a few seconds in a cameo as a neck-strapped-keyboard playing street musician.
The band Phoenix are featured as The Chefs. Phoenix also played on the Lost In Translation (2003) soundtrack.
Rapper Rick Ross was initially going to perform "Santa Claus Wants Some Lovin'" with Murray, but when he became unavailable, George Clooney filled in.
Bill calls himself The King of Christmas which his brother John Murray's character calls him at the end of "Scrooged".
This marks the second time that Sofia Coppola has directed Bill Murray. The first time was in Lost in Translation (2003), for which Murray earned an Oscar nomination.
