LMAO!! Wow! I guess it is true! These movie studios will go to any length these days just to try and get some more sales. That's pathetic! Photoshopping is overrated, and clearly they did a lot of that for the poster. I didn't notice at first until I figured out where to hover over and then it was really obvious.
It's not that noticeable. They've done the ^ the stuff Tragic Kingdom said and her boobs are slightly pointier i.e. drawn out and less close to the chest. It's like extra toning and things are abit bigger.
The Arthur movie poster now, very noticeable differences.
