Douglas Howe has a great list of rain scenes in movies over on Idol Chatter, including two of my favorites, “Singin’ in the Rain” with Gene Kelly and “Say Anything” with John Cusack.
Cusack for some reason is always getting drenched in movies. You could fill a whole list of great rain scenes just with Cusack performances.
A guilty pleasure of mine is the last dance number — in the rain — in “Step Up 2 the Streets.”
I love the rain scene in “Garden State.” And one of the best dance numbers ever is “Isn’t it a Lovely Day to be Caught in the Rain” with Astaire and Rogers in “Top Hat.” Oh, it is a very lovely day indeed.
