In the UK at least BAtman was the first ever 12 rated cinema release. I remember this very clearly as I was 11 when I went to see it and my mum made a joke that I couldn't go (of course I went anyway). There was also a lot of stuff in the press at the time about Batman being the first film to be given a 12 certificate in the UK so Weekend at Bernies must have come out after it.
On the Goonies fron so this isn't O/T. I bought the DVD as soon as it came out as I love this film and also wished that I was a Goonie when I was kid.
I think they should do a sequel and have all the original characters grown up and their children becoming the second round of Goonies after hearing all about their parents adventures. This way it wouldn't need to involves SLoth, Mama or One Eyed Jack, they could have a whole new Adventure. It would be so cool, and get a whole new generation of Children wanting to be Goonies.
To keep the authenticity it would have to be written by the same team and directed by Richard Donner.
