this was one of those films where the premise made me groan. I pictured a tedious slightly cheese-ball dated experience. Boy was I wrong. This movie was so well-done, so well-written and directed that I didn't want it to end. One setting is all that exists and Hitch certainly knew how to stage this and make it work. Hitch is truly the master at 1 set movies, from Rope to Rear Window to this. Intense! I consider it one of his greatest films alongside such classics as Shadow Of A DOubt and the afore-mentioned Rope and the dark comedy The Trouble With Harry.
Of proof of Hitch's genius, look for his cameo. Classic!
This is a must-see!
