unfortunately it does n't get much more formulaic than one tough cop .
there 's the renegade cop with the loser partner who has to many problems to explain .
the renegade has to prove his good name and is trapped between the good guys , the bad guys and some woman who really has nothing to do with the story other than being there for the purpose of providing sex for the hero in the middle of the film .
bo dietl ( pronounced deedle , baldwin ) is one tough cop , a guy who is being investigated by hardass fbi agents due to his association with the ny mafia .
on top of that problem , he has a drunk , gambling addicted partner ( penn ) who has a penchant for collecting parking tickets ( i guess cops are n't immune ? ) .
then , throw into the mix the femme fatale ( gershon ) .
right there you have plenty of ammo for a decent cop drama .
but right in the middle of the film , they throw in a completely un - related plot point .
dietl and his partner duke try to solve a case that they have been warned to stay away from .
the film spends over half an hour tracking the case of a nun who was beaten and raped to near death .
once the case is solved , the film shifts focus back to the mafia issue .
whatever neat mesh the screenwriter wanted to create between the two stories failed miserably . aside from being asked to accept michael mcglone as a mafioso ( an insult if you ask me ) the performances were pretty good .
baldwin , though he occasionally slips into an impression of his brother alec , does a fine job as one tough cop .
penn , who also slips into an impression of his brother sean , is even better as a loser tough guy cop .
what one tough cop lacks is originality .
this film offers nothing new .
nothing that you ca n't get from any cop film .
it screams sidney lumet all over the place , perhaps because it was produced by marty and michael bregman , producers of lumet 's dog day afternoon and serpico .
but even the masterful sidney would not have been able to make one tough cop into a good film .
too much else is lacking .
i also saw the boom mic pop into the top of the frame twice early on in the picture , something that i almost never notice .
but once i saw that , i had it in the back of my mind every time i saw a medium or long shot .
at times , i was hoping to see it .
one tough cop is n't laughable , nor is it a terrible film , but it just is n't unique .
it is a classic example of a film that did n't need to be made .
but one thing is for sure , it could really use a better title .
a completely un - related plot point this film offers nothing new it just is n't unique failed miserably too much else is lacking
