The titular Tuxedo worn by Jackie Chan was bought at auction by Podcaster Andrew Panton of "The Regulation Podcast" in 2022.
During filming in Toronto, Ontario, Jackie Chan and Jennifer Love Hewitt appeared on an on-set webcam and interacted with fans.
The first time Jimmy Tong (Jackie Chan) takes Clark Devlin (Jason Isaacs) to the hospital, he meets a woman who keeps asking for "Dr. Angelo" When Jimmy visits Clark, the same woman can be heard over the loudspeaker asking for Dr. Angelo.
When Jimmy (Jackie Chan) goes through Mr. Devlin's (Jason Isaacs) address book looking for "Walter Strider", he finds phone numbers for Claudia Schiffer, H. Norman Schwarzkopf, Stephen Sondheim and George M. Steinbrenner III. All of the numbers have special characters inserted to ensure that they are not real numbers that people might try to call.
