Poor Dax. Poor, poor Dax.
I feel sorry for the guy, but I’m afraid he has no one to blame but himself. After all he is not only the star of the film, but also the writer and director. And I wouldn’t be surprised to find out that he is also doing the posters.
Just for future reference, if you are making a parody film that doesn’t mean that your poster has to be horrendously ugly. Also, if you are going for the low budget action film aesthetic in the poster, there is such a thing as too much authenticity.
I think the comparison to the very similar, going for the same effect poster for The Other Guys is interesting. Sometimes less is more, lose the awful background in the poster above and it would already be 100% better.

I remember more the three posters made for Transporter, the DVD’s covers are very similar, also de first movie poster. What do you think?
