In the left bottom corner of the receptionist's desk is a glimpse of a postcard size sticker that has the numbers 01.20.09 which is President George W. Bush's last day in office.
Exterior of Manhattan Criminal Courthouse is actually Baruch College located in NYC. Production paid a little under $7,000 (as well as clean up costs) to the school for the use of their exterior.
The scooter itself is just powerful enough to make it technically illegal in New York City, which permits electric scooters but has banned engine-powered ones like Charlie's. He's a bit of an outlaw.
In the bar scene, Alan gets soaked by Charlie's drink, covering his face, shirt, tie, and coat. Alan then turns and when he exits the door, he is completely dry.
What happened to the scene from the trailer of Charlie and his family playing on the bed?
A
Trailers are sometimes made before the film is finished so some scenes included in the trailer may be cut from the film during editing.
Q
What are the differences between the UK DVD Version and the Uncensored Version?
A
After Charlie selects the song "Birds Of St. Marks" by Jackson Browne on his Ipod, the UK DVD skips the whole rest of the first session as well as 2 additional sessions and Charlie renovating his apartment. These scenes were probably removed for copyright reasons. A detailed comparison between both versions with pictures can be found here.
