A movie about a man who travels to another planet using a pocket watch. There he falls in love with a girl, he somehow comes back and spends his life on earth. At the end of the movie he pretends to be dead in a crypt just that someone who believes he still has the watch comes and robs his, but instead he steals the watch from the thief and goes back to his long lost love. Its kinda blurry the story but this is all I can remember. Hopefully one of you you’ll remember the movie’s name😭
That sounds like the 2012 fantasy film John Carter, which was based on a story by Edgar Rice Burroughs, the author of the Tarzan books.
