Genre Collage
Mixing several genres in 1 film, such as crime, romance, horror and absurd comedy. The clash between them keeps you from settling into a single way of watching.
Some Like It Hot
The film is 3 genres at the same time. It is a gangster film (the massacre and the chase after it), a screwball comedy (the disguise and the romantic tangles) and a farce (the final act, which gets more and more absurd). Wilder moves between them without announcing it. A gangster scene can turn into a comedy scene within the same exchange.
Hail, Caesar!
The film jumps between the genres a 1950s studio would make. A Roman epic, a Western, a sailor musical, an aquatic spectacle and a comedy of manners all appear. Each one gets its own style, and the clash of them is the joke.
