Corrected entry: In the scene where Arnold is at the front desk of the hotel and retrieves the paper from the safety deposit box, he asks for a pen. The clerk gives him a red pen to write on the back of the paper stated "for a good time, ask for Melina". When the scene cuts to Arnold writing on the paper, the ink is black. When he returns the pen to the clerk, it is red again.
Corrected entry: The main plot is similar to a futuristic Japanese anime called "Space Adventure Cobra" (1982). In the first episode of the series, Cobra believes that he is a normal guy, but discovers accidentally that he was a secret agent who deleted his memory and changed his appearance to run away from his enemies. This happens when he goes to a place where customers pay to experience their fantasies using a kind of brain-PC connection (just like in Recall). He dreams he is a special agent hunting criminals in space but eventually realizes he is just recalling who he used to be. http://www.imdb.com/title/tt0163494/.
