David Lynch: Lost Highway, Mulholland Drive, Inland Empire

Lost Highway, Mulholland Drive and Inland Empire all have very similar qualities when it comes to conventions of David Lynch films. The most obvious one is the narrative; none of these films have a clear linear structure and most of the scenes are in an unusual order which would initially be nonsensical to the audience. The dialogue itself in these scenes also occasionally is quite nonsensical, making the audience uncomfortable as they don't know what entirely is going on. Dream sequences are a common aspect of the film (often explaining why nothing makes any sense) which usually involves obscure angles and lighting to differentiate from the real world.  

Colour and production design in these films is also important to Lynch - most of the main body of the film involves exaggerated colours, expensive cars and unique decor, to both represent the Hollywood industry and the American Dream, as well as to contrast against the harsher and darker sides of the story. In the sequences where things typically get more messed up, the lighting is much darker, usually with tinted filters (particularly in dream sequences) such as the red tinted prostitute dance sequence or the blue tinted sex scene in Inland Empire. 

Other conventions to note of David Lynch films are the use of lesbian activity (mostly apparent in Mulholland Drive) and telephone scenes (most apparent in Lost Highway), which appear often as something iconic. The two main female characters are almost always a blonde and a brunette also, to exaggerate a contrast in the characters, and by extension, represent the light and dark sides of human personality.
 The reason these films inspire me is because I admire how Lynch can take a concept of a Hollywood film that seems so simple and then turn it into something completely insane, yet so beautifully put together to make it seem artistic as a way of portraying meaning to the audience. He doesn't make films like this particularly for a certain audience in the way other Hollywood films are made for the purpose of the audience's entertainment; these films are what Lynch makes from his own ideas for himself to simply show an audience his own feelings towards the industry itself.
