Shutter Island (Scorsese, 2010) – tonal montage to indicate protagonist’s false reality/subjective reality (use of blues/greys when audience is submerged in Teddy’s reality) 

Psycho (Hitchcock, 1960) – rhythmic montage to dramatize and emphasise the content of the scene (to associate this series of events with a musical climax for the audience) 

Inception (Nolan, 2010) – intellectual montage is used as a metaphor (aided by the context of the film itself) to indicate to the audience that there is still a question of dream vs reality, and introduces the idea that people are controlled by an unspoken force (whether fate or a higher power etc.) just as the fabrication of dreams is controlled by the presence of gravity.
