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.
The crew used a giant tow truck to pull the big rig down the highway. It had cameras mounted to the outside. It's really Jason Statham hanging off the bottom of the truck. "I had a wire up my leg and they assured me I was quite safe. There was a lot of hanging on to do."
The film was considered a possible influence behind Serenity (2005). In that film, the main protagonist Captain Malcolm Reynolds is a former soldier turned space pirate. In this film, Frank Martin is also a former soldier turned hired driver and mercenary. In both films, both characters become protectors of their cargo, beautiful young women, whose clients and the government are after.
