As a child of the 60's I certainly saw a lot of Tarzan, there was a TV series that ran for a few years and I think they showed re-runs of those Weismuller movies every Saturday. Never was a huge fan, but I can still do a Tarzan "Yell".
There was that movie that came out in the 80's, can't remember the name, Greystoke, Lord of the Apes, or something like that. I looked forward to seeing it, but it turned out to be a disappointment. Maybe this one will be better, but it sounds as if it's a replay (with a few differences) of a story that has been told so many times. Oh well, hope for the best.
