I'm going to LOVE this group!
Charade - Audrey Hepburn and Cary Grant - doesn't get better than that. 
Or sexier. Or better banter, line delivery and timing.
I will always always laugh at: Tootsie and Arsenic and Old Lace.
I was born in 1973 - so for me - Classics are anything from my childhood - and Tootsie was a classic from my child hood.
Best Suspense Movies - Rear Window and Niagara. It's completely possible (particularly with Niagar) to have a terrifying murder 'on screen' but not be able to see it at all.
Best Love Stories - The Ghost and Mrs Muir and The Shop Around The Corner
Guilty Pleasures - Regardless of how many times I've seen them . . .
Marty, Miracle in the Rain, High Society/Philadelphia Story, In The Heat of Night, Stormy Weather, The Petrified Forest, and Gilda.
Ohhh - I'm going to love this group!
