I don't know if there's already a forum for this...probably, but it's not active anymore. So I'm starting a new one. This is a very simple game. All you have to do is post a picture of the movie WITHOUT any text or clues on it whatsoever. So it should be like a still from the movie or a screencap maybe. The next person comments what it is and posts a picture of their own for the next person to guess.
If you do not know what it is, try not to post a new picture right away. Instead, ask for a clue. Examples of clues you may give:
"Also starring ____"
"It was made in ____"
"Starts with ____"
If nobody guesses your movie within a day, you may say what it is and continue the game with a new picture.
