Thanks 2J. Happy holidays!
These two movices are so different from others. You only watch two people keep talking from the begining till the end. "Before Sunset" is the one I watched first. I then found in the Internet that "Before Sunset" is just the sequent to "Before Sunrise". You can find "Before Sunset" in my blog if you dont' want to wait.
I also watched "On the Golden Pond" which is beautiful and touching. It's starred by Katheine Hepburn, Henry Fonda and Jane Fonda.
