I'm familiar with all of those. I thought Hitch redid a few of the movies he made, particularly the ones he made while he was still in Britain. I may be wrong. They've certainly butchered the remakes he wasn't involved in (with the possible exception of Rebecca).

I haven't seen the remakes of The 39 Steps, but I suppose you won't be surprised to hear it's over there in my private movie cabinet. I haven't seen Gaslight in years and skipped it the other night because I wasn't in the mood. Not my favorite. The original Shop Around The Corner was delightful as was it's musical version, She Loves Me.

I may have to disagree with your exclusion of Hepburn from remakes, though. Part of it is that I miss Spenser Tracy more than Kate, but not much.    I'd kinda like to see a remake of Adam's Rib or even Pat and Mike. Besides, What's Up Doc was a pretty remake of Hepburn and Cary Grant's Bringing Up Baby.
