This design is, in general terms, fine. Minimalistic and clean. But I would like to raise two objections:
1) I really hate the proliferation of QR codes in posters. I knows, this is a highly personal preference, and it probably marks me as some sort of neo-luddite, out-of-touch, old person, but there it is.
2) Quick, what’s the name of the film? Well, you probably read this post’s title, so you know. But think of this from the perspective of someone encountering just the poster. As a general rule, if you have a somewhat long, somewhat hard to remember name, the last thing you want to do is hide said name by making it seem like a list of actresses that are in the movie.
Of course, I’m ready to admit that the biggest problem here is that the name is awful (from a marketing perspective at least) and that it is very hard to work it into an image. And I sympathize with the poster designer’s wish that the movie was simply called M. But it isn’t, and just giving up doesn’t seem like a good answer.
