this is a pg. because it has mild threat and also dangerous behaviour
this is a u rated movie because it has no vilonce and has mild threat and ishough it could look scary or dangerous that the woman keeps nearly dropping the babies it is presented as a joke - the audience know it is funny not scary.
this is a 12a becuse it has some shooting but not a lot and has a little bit of vilonce in it
this is a 12 because it has moderate bad language
deadpool is a 15 because there is a lot of violence and swearing
this trailer is a 15 however the actually film is an 18 film because it is disgusting as it also has a lot of violence in it that the audience can see
