Julie and Julia was released today, I believe. Anything Nora Ephron does is fine with me, and if you add Meryl Streep to the mix, I'd walk 5 miles to see it.
Here's the trailer for Julie and Julia: http://www.julieandjulia.com/
The other one I'm interested in is Eat, Pray, Love but I don't think it's out yet. Julia Roberts stars in this one, so it could be great or not. No clips available, but when they are, I'll add a link to this post.
Have you seen anything this summer that you'd recommend?
