Basically, post a picture of your favorite moment(s) in a movie you like. Then, other people can guess what movie it is or just talk about the movie.
The picture should do at least one or two of the following:
>Show your favorite part(s) of the movie
>Sort of capture the movie (as if it could be put on a poster for the movie)
>Be recognizable enough to where someone could guess what movie it is
GIFs are acceptable, I guess.
