Mick Gould is Michael Mann's technical advisor on fight scenes and use of weapons. Ex special forces, this video clip shows Mick Gould training Colin Farrell for that opening scene in Miami Vice. The scene has a similar flavour to the nightclub scene in Collateral where Tom Cruise does a similar floor crunching move. For the girls, see a sweaty, topless Colin Farrell... if you must!
I have to say, Mick Gould shows the moves with frightening efficiency.
