Okay so I remember seeing an ad for this movie that aired before I saw Hellboy on DVD, so that would mean it came out around 2008 or so.
Basically the overall plot of the movie is that there’s this guy who wakes up one day and no one remembers that he exists, not even his wife. Also I think he writes novels.
Its not much to go on, but if anyone thinks they know it…
Mr. Destiny?
