The last house on the left

Here is two film posters from the film 'The last house on the left'. the first one is the original film and poster to come out. (1972)

For my poster i am comparing these to posters to see the conventions and to see which is more effective on the audience.

The modern poster for the last house on the left shows the audience the cast and the house in which it takes place. i like the contrast of the red and white against the black and may well use this effect.
