Every well-known movie has specific scenes it is famous for. This is the case with the bike fight scene in John Wick: Chapter 3 Parabellum, where we take a glimpse behind the scenes to see how the production team made that action choreography.
In every movie starring celebrities dangerous scenes have always been a subject of caution. Sometimes stunt doubles are used, other times other types of trickery is involved such as filming on a chroma screen, or keeping the actors safe by various grip means. When car and bike chases are involved often they film the vehicle standing still on a platform which is pulled or pushed by another vehicle, like a truck. If they don't show the wheels, they are perfectly fine. In the case of John Wick 3 we have a fusion between green screen and locked vehicles on moving platforms together with the camera operator dancing with the actors in perfect choreography.
One case for a fake-looking VFX shot is the lighting. Often we see night car-driving scenes filmed on a green or a blue screen and the light on the faces of the actors is not changing despite the changing environment around them. The DP of John Wick 3 didn't make such a mistake, but they simulated tunnel lighting, which together with the brilliant work of the CG artists, made the scene exciting and believable.
