I picked up a DVD of Goonies at my local big-box store earlier this week because I've always loved the movie and the box listed a commentary track. I don't know if there are multiple DVD versions of this out, but the one I have has the ISBN of 1-4198-5512-3.
I was surprised to see that it was directed by Richard Donner. Stephen Spielberg wrote the story and he was one of the producers, but didn't actually direct the film. It shouldn't have surprised me, he's directed other movies that I love, particularly the first Superman movie.
The commentary track is really cool. It has Richard Donner, and most of the principle cast members who played the kids in the film. It's obvious that they liked making the film, had a lot of fun doing it, and it was neat for me to be able to watch it together and comment on it.
