I also really liked That Thing You Do. I know Hanks is a big collector of old 45's and loves that era of music. I wonder if Forrest Gump winning the Oscar was what gave him the pull to direct That Thing.
I'll have to watch Larry Crowne!
Another Hanks flick currently on Netflix that I highly recommend is Charlie Wilson's War, also starring Julia Roberts. I was not interested when the movie first came out, but I gave it a chance and was surprised by how much I liked it. Great dialogue too, thanks to Aaron Sorkin. Phillip Seymour Hoffman was amazing in it, easily one of the best parts he's played.
