Credits are almost always used at the very bottom of a conventional movie poster so this is where I chose to place mine so that it would fit in with posters that are pre-existing. At the very bottom of the poster, and in a slightly darker tone than the rest of the text, it doesn't distract us from any of the text on the poster and we can read into but only if we go out of our way and choose to. I also decided to use sponsors surrounding my credits as this is a conventional location for them to be found, and it creates an affect on the viewer. If the viewer identifies that the movie has had top end sponsorship from reliable media groups, then they will be more likely to trust the film as they will already have associations about previous films the sponsors have invested money in.
