Action Films Conventions - Olympus Has Fallen

This is the poster for Olympus Has Fallen:

• The poster is dark in colour which displays a real contrast to the writing and the White House exploding in the background. This highlights the action and is likely to draw in viewers.
• The fonts on the poster are bold and brightly coloured which suggest that something big is going to happen.
• The army helicopters in the background along with the White House exploding, suggests that the USA is in a lot of trouble.
• The USA flag is on fire which suggests a terror related plot.
• The 3 actors are all close together which displays some bond between them. 
• The mention of a previous action film 'From the director of Training Day' suggests the action genre further.
