Super Spys vs Questionable Sorts
Roy Miller(Knight & Day) and Jason Bourne(Bourne Trilogy) face off against Charlie Wax(From Paris With Love) and Frank Martin(Transporter trilogy). Roy and Jason meet up by accident in New York after both easily take out a team of agents trained specifically to bring them down. Before fighting each other, they realize they're both fugitives from the law, and impressed with each others skills, decide to team up and increase their chances of survival and completing their missions.
The government goes to extreme lengths, and hires Wax and Frank Martin to bring them back, no questions asked, alive.
Somehow they get into a lengthy chase, then all crash(unharmed) on the docks. Any weapons they had fell into the water, so the fight is a 2 on 2 brawl, and any objects lying around can be used as makeshift weapons.
Shards of glass, pipes, rope, etc...
Who takes it? If Wax is too much or too little, he can be replaced with Bone(Blood & Bone)
