This American Rogue poster isn’t exactly subtle, is it? We have a big ass alligator, jaws wide open, trying to eat a bunch of ragged letters. Which is meant to convey that the movie will have a giant ass alligator which will try to eat a bunch of people. No actors in the poster because, honestly, who cares? They are just the food. It’s all about the beast.
This poster strikes me as being narrowly targeted at a core of horror lovers. The total focus on the monster and the amount of it that is shown doesn’t seem compatible with trying to go for a broad sell. Compare that with the previous Rogue poster, which took it’s inspiration from Jaws and made the movie look a lot more like the kind of suspenseful horror that can bring in nice crowds.
I guess they just didn’t think Rogue would be able to get big numbers in America, and decided to focus just on the real horror fans. It’s also possible that this is not the main poster they will be using and that it was created just to get the horror fans excited. But my money is on the first option.
