Film posters say more about the actors/characters than we think..

There are undoubtedly some actors that we categorise playing certain parts e.g Colin Firth playing the English gentleman having some sort of awkward affair with a woman, or Helena Bonham-Carter playing a crazy woman (obviously there are some exceptions). One of the key conventions of a movie poster is to inform the audience of what the film is about, and what the characters are like and the genre of the film.
I've done some research into the same actors in different films and there are some hilarious comparisions. I found the lack of imagination of some of the poster designs in some of the top Hollywood films.
It was the case that in the old days where Hollywood cinema starring Judy Garland and Marilyn Munroe that the production companies actually owned the stars, therefore there way of advertising was by plastering the names or pictures of the stars all over their film posters. This seemed fair, if you have the likes of Marilyn Munroe in your film you may aswel show off your assetts.
However it seems now-a-days that there are only about 10 actors in the world, and in every film poster they seem to be doing the same thing:


 Colin Farrow is always staring into the corner of the poster....




Jim Carrey has an extravigent expression on his face and very flexible arms!




Johnny Depp doesn't appear to like the top of his head..




Jennifer Anniston is always with a man and looking very glum..


Looking at these posters has made me realise that its not hard to create an eye catching poster, Personally I didnt want to have any actors on my posters because I dont like that way big Hollywood blockbusters drive the sales of their films by utilising the actors fame.
