In the movie, LesterCorp occupies floor 7 and 1/2 of the Martin Flemmer building. According to IMDb, Craig discovers this at the 7 and 1/2 minute mark of the movie. This could be a coincidence, but it could also be deliberate.
The number 44 also has some significance in the movie, as this is the age the "host" must reach before they become "ripe for occupation".
Are there any further significance to these numbers, or other references within the movie?
