After re-viewing the trailer, I've decided that Christian's avatar on the forums came from the wall in the movie. Am I correct?

Well, sort of. Yes, it's on the wall in the movie trailer, but it's more than that. The picture was drawn by his sister, Lissa. So, it's not really from the movie so much as it's a picture of him that he has hanging on his wall that just happens to show up in the movie.
