I've seen The Fortune at least 20 times, and I've also taped it whenever it's played on cable, but I desperately want the DVD of it (Region 1; I did purchase a Region 2 version). I think it's borderine criminal that some of the best movies ever made (such as this one and Scenes from the Class Struggle in Beverly Hills) are not being released on DVD. It's also incredibly stoooooopid of the normally greedy Hollywood money men.
You want another belly full of laughs? Mixed Nuts by Nora Ephron, with a stellar cast of comedic talents! Laugh, I thought I'd die!
Add one more, The Pest, but be high on something (ice cream, sugar donuts ... whatever) when you watch it ~ it's insanely zany. If you don't need a bedpan 10 minutes into it, your humour scale is minus zero.
