This is a typical poster for a thriller. Dark, two floating heads, white and red letters. All very, very common for this type of film.
This second poster is a little different, and it caused some problems. Some people in Boston, including anti domestic violence groups, were upset with the poster and called for it to be taken down.
I find it hard to believe that a poster could lead to more violence because it says “I Shot My Wife”, but apparently these people feel differently.
