Sorry twcrash, but WhiteKnight77 beat you to the answer a few days ago (see page 15)
Next movie is one of my favorites...
Try to go without Googling the following hints...
Filmed almost entirely on one set.
Has a 100% rating on Rotten Tomatoes
Except for the final scene, no personal names are used
An extra 1,000 bonus points to the poster who (without the aid of Google) can give the name of the actor pictured above. As an added bonus 1,000,000 points will be given if you can give the character's name in the movie!
