Ding, Ding, Ding, we have the winner!!!
This was at the height of his..uh..career..yeah, he was such a big star at the time he had his own butt double for Robin's nude scene. I guess they thought it might bring in the women for the movie. Costner didn't even attempt a British accent, which was a shame because that would probably have been the most entertaining part of the movie.
Costner’s lack of even attempting a British accent for that movie always mystified me until recently. I read that, when the film was being made, there was another Robin Hood movie in production-—I think with Patrick Bergin and Uma Thurman. Both movies were in a race to be finished, because the first one done would be shown as a theatrical release, while the loser would be shown on TV. They filmed Costner as is to save time, planning to dub in the British accent later, but in the rush decided to skip the dubbing. Costner’s movie finished first and got the theatrical release.
Go back and watch it again...it seems like he tried it early in the movie and they told him to just forget it...it is actually pretty funny.
Costner was terrible in Robin Hood, but Alan Rickman was great!
