The trailer for the film showed Frank deflecting a missile with a tea tray. In the same scene in the film, the assault on Frank's house, there is no sign of this in the released version. It was taken out at Jason Statham's request because he didn't think audiences would believe it.
Frank's car is a BMW 750i E38 (pre-facelift). The car in the movie is the only one ever produced with a manual six-speed gearbox. This information is obtained from the full-length audio commentary available on the DVD. People have made conversions using the manual gearbox from the BMW 850CSi E31 but that car is genuinely rare.
When Lai is using the computer, she browses through several other pictures before finding Wall Street's. The other pictures are all of crew members and the names next to the pictures are all jokes ("Gordon Zola", "Christiane Isme"...).
The US poster lists Corey Yuen as director and Louis Leterrier as artistic director. The European release lists Yuen as action director and Letterier as director, similar to the opening credits of the film.
