Mean Johnny Barrows (1972)

An ex-star running back returns from Vietnam.

He was kicked out of the service for a scuffle which wasn't his fault, and is on the streets looking for work.
Wandering into a kitchen looking for a bite, he unexpectedly runs into a former (college) rival, owner of a 5-star restaurant.
The old acquaintance offers him work as an assassin, but Johnny turns him down.
After his "friend's" father is killed by rival dealers, he reconsiders his answer, due to a semi-romantic subplot.
The racial hints are hilarious, including a scene involving a perfectly-timed stroll by cops just as Barrows is having a conflict in a gas station.
Equally as comedic is all the kung-fu action in store. I think this one deserves a silver star, per se. 7/10
