The movie takes place the same day that the film premiered - June 29, 2010
Martin is teaching a class about "A Christmas Carol" which is very similar to the situation he's in, revisiting his past while reassessing his relationships.
The classroom scenes were filmed in the director's alma mater, Lindbergh High School.
Martin stays awake for about a week. He comes close to beating the world record of 11 days held by Randy Gardner.
