Looking at how the film "Football Factory" uses conventions and techniques of thriller films. (Independent Research)

The film " Football Factory" despite not falling into the thriller genre , the film uses many techniques and conventions that are used in a typical thriller film.

The use of bleak, dull lighting in certain settings such as the pub connote an eerie feel to the setting which at times depicts the characters personality.

The use of noir lighting in the tunnel where one of the main characters (played by Danny Dyer) gets beaten up connotes fear and vulnerability. He's vulnerability is also caused by the characters drunken state.
The characters playing the role of 'hard men' can also play the roles in thriller films. Often they are depicted as thug-like, set only on a motive to kill. That motive is in revenge or to conceal something. The characters within the film "Football Factory" are all over-reactive thugs. They all have a stereotypical depiction of them as they have a thugish look to them. The costume worn is that of what would be considered today as 'Chav' like. The characters wear tracksuit-bottoms and short-sleeved shirts/football shirts. On occasion a few characters wear suites showing their status within the group.

The violence within the film is very high in content. The use of close-ups capture the violence that occurs, making the audience feel more involved in the many brawls that feature. At one point in the film the the camera lense is splattered by blood, again involving the audience. When in the action scenes the camera tracks movement, incorporating many different shot types such as close-up, tilts and low angle shots.
