Harold and Kumar (Comedy)
Props: In Oldboy the main actor is holding a hammer. This connotes violence. The stance in which it's held connotes that he's ready to inflict violence on someone else. The other two posters have no props in the posters. During the clip I posted he defends himself against a horde of enemies which shows Old Boy has a mature and violent theme. In Harold and Kumar (The clip); Harold holds a bag of weed while the black inmate holds a reading book. These connote how the film deliberately goes against stereotypes. The props in Old Boy are used to demonstrate a violent act whereas in Harold and Kumar they're attempting to tackle stereotypes.
Costumes: Harold and Kumar both wear average clothes which connote that they are normal people and no-body one special. This is similar to Old Boy as the main actor is actually wearing normal clothes as well. Both show that the people involved in both movies are normal people.
Lighting: Apocalypse Now has high contrast lighting towards the sun but is tinted to signify the horizon. This connotes that the poster is attempting you to look at the horizon. This is different as Old Boy has a much low-key lighting to connote that it's a serious thriller and Harold and Kumar has bright lighting which connote it's a comedy
Setting: Apocalypse Now is set in Vietnam and the poster shows a peaceful environment. However it's filled with Fog which connote that something sinister is upon the horizon as there is a sun set and river leading there. It's a chilling setting. The Old Boy poster is set in a run-down building with low lighting which connote that it's not a good place.
Actors: Apocalypse Now has Marlon Brando who was the Godfather. He was a highly influential film actor. If he was starring in a movie it would be likely someone would be watching it. Harold and Kumar have an Indian and a Korean playing each part. They are challenging stereotypes by having common names for each ethnicities but at the same time go against them.
