Key conventions on Trailer and Poster

 

 

The genre of the film is comedy.
The key conventions on the poster are:Title,Central image,Production blurb,Slogan at the top.It also shows that its funny as the way they are dressed,and that they have a baby wearing sunglasses like the person that is holding it.
The key conventions of the trailer are that:they picked the most funniest scenes to be in the trailer to show that its a good and funny film.Also you can hear modern music that would go with the film/scene and hear what the people are saying in the scenes.
I think the target audience is between 15-30yrs.
The film promotion was successful as it was a comedy film and it included funny scenes that you wouldn't normally expect.
