Olivier Megaton views the "Transporter" franchise as being somewhere in between the James Bond and "Die Hard" series, with a slight edge to "Die Hard".
All the car stunts were performed in real time, without models and little to no CGI, which naturally provided its daily dose of challenges to Michel Julienne's stunt team.
In one scene, Frank tries to save his sinking Audi by inflating body bags with the air from his tires to make it float to the surface. Though seemingly unlikely, it may be possible since car tires are filled with compressed air. Deflating all four tires may provide enough expanded air for the body bags to make the car float.
Frank's car almost has a crash with a Renault 25. The Renault has a license plate starting with "RO" and the Romanian flag, but the ID number is not a Romanian valid car number - it's actually Hungarian. (In Hungary the car ID is, for example, ABC-123, but in Romania it's XY 12 ABC, where XY denotes the county).
After Frank was hit in his house and fainted out, he walks up in a facility, in the first shot, there's no bracelet around any of his wrists -only the watch around his left wrist, but in the second shot the bracelet appears suddenly around his right wrist.
