I saw it once years ago but Sharky's Machine was a pretty good cop flick.
Exciting film. Henry Silva plays a great psycho as usual. Check out another good Burt Reynolds flick, Malone.
I did not really knew him as an actor. I have the feeling that he was way more popular in the Us than outside the US. Also he was a guy from the '70 and the '80. he had quite less rearkable movies in the '90 and after. His last real good movie was Boogie Nights
Anyway, RIP to him
