I have to confess.....I love this movie. I think I've watched it over 300 times, and I'll probably watch it another 300.
Say what you want to about Meg Ryan being too cute, about the plot being predictable, whatever. I think it's just....jivin'. It's a neat love story, about the actions of boy meets girl, fate and love, and Albert Einstien's convertible. Throw in a comet and a few wacky physicists, well, it's just pure fun. I wish to heck I could find the score somewhere; the blend of do-wap and Mozart is as much fun as the movie itself.
I'm prejudiced because Tim Robbins is my favorite actor, but all the acting in this goofy, off the wall film is top-notch. Though it's not one of the late Walter Matthau's most famous roles, I personally think it's one of his best, and I can't think of anyone better to play the eccentric Albert Einstien.
One of the most beautiful things about this film is the accuracy of the set and costumes. Not just Meg Ryan's picture-perfect 50's dresses, but the buildings and vehicles, and especially the heavily wood-panelled bungalows favored by the rich during the late 50's; they're so time-perfect you can almost smell the Lemon Pledge.
Incedentally...look for one of the funniest performances in one of the experiments by Meg Ryan's movie fiance, "Excremental Psychologist" James Moreland. I'm not sure who the actor is, but in the background of his lab is a student driven psychotic by a "time depravation experiment", and his physical humor and antics are about a thousand times better than anything from SNL in the past decade.
By the by, this makes a perfect date movie, and is mild enough for kids...but still fun for adults. It's just all around terrific, and a great buy.
