- In many crime films, there is gang rivalry. This is a popular cliche as crime is linked to police, and in the news there is a lot of gang rivalry. By using this cliche the audience are able to get involved in the film as they know it is linked to a real subject going in the world that they want stopped, and in crime films most of the time the good guys stop the gang rivalry to make everything okay again.
- Another popular cliche is good cop, bad cop interrogations. Using this in films is good because the audience likes to see the different sides of the police, to see who manages to get the information they need out of the bad guy. Also it can help them decide who's side they are on, either the good cop's or the bad cop's.
- Most of the time there is a 'rat' who is an undercover cop pretending to be part of a gang or on the bad guy's side. This is a effective thing to do as being undercover they can find out a lot of stuff the gang's wouldn't tell anyone else as they trust the rat to be trustworthy and faithful towards them.
- Sometimes when the crime people are investigating, there is a dead body in the trunk of a car. This is a popular thing to do as the audience are led to question how long the body has been there for and who has done it, and why they have left the car and body alone for the police to find. As there is always a reason behind it, the audience feel the need to continue watching it.
- Never in crime films do they ask for ID. There could be someone the cops are protecting in custody, and the bad guy can walk right in past the guards, as the guards just assume they aren't there to kill the person; when most of the time that is their sole reason for being there. This a popular cliche that appears in many crime films, that the audience most of the time expect. It is effective because the audience still get frustrated at the situation even though they know it was going to happen.
- There is also a lot of violence in crime films, as when you think about the police and detectives, their job is to do with violence, as they investigate murders and assaults etc. This is effective as the audience can relate it to real life and it makes it seem more real instead of it just feeling fake.
- Most of the time there is also a corrupt cop, who doesn't play by the rules completely. He may sometimes let the bad guy's off or agree with them etc. This is effective as the audience can have someone they don't like and don't agree with to help them choose sides.
- There is also 'the neighbourhood' where all the crime takes place. This is mainly because the gang's are fighting for 'their territory' and don't want another gang to take over. 'The neighbourhood' can also be where the gang members have grown up, and would do anything to protect it.
- A lot of the time there is a respected gang leader, and what he says goes. Most of the time he is the person the cops want to catch most, as without him there is not a gang. The effectiveness of this is that the audience see the gang isn't so big and tough without their leader.
- Sometimes there is also a corrupt doctor/lawyer along with the corrupt cop. The corrupt lawyer may not act how he should and help the bad guy out, or possibly take a bribe etc. This cliche is effective as it may happen in the real world as well as the film, and may make it easier for the audience to relate.
