I'd 2nd (or 3rd or 4th or 5th?) Princess Bride, but be aware (if it is something that you pay attention to) that there is some mild swearing in it. I watched it as a young adult and LOVED it. Watched it multiple times and laughed all the way through every time. Years went by and I thought it would be something my kids would enjoy. So we put it on....
I was unprepared for some of the language. Again, it is very mild, but your mind doesn't register ANY of it when you are 20 and so I thought it was a totally clean movie.
So, while I highly recommend it, I would be aware, if that is something that you monitor. You can do the imbd thing and see exactly what the language usage is. It has been several years (again) since I have seen it and can't remember details.
