But...but...but....I LIKE Zardoz...
Did you ever see Sword of the Valiant, where Connery plays the Green Knight? It was an little film that combined Sir Gawain and the Green Knight with Yvain and a smattering of other bits of Arthuriana
But you are right about the second Highlander movie. Nothing under the sun could have saved that miscarriage of sequelity...
Zardoz is much akin to Showgirls: A movie so pompous in its delusions of relevance, so poorly acted, and so implausible overall that the presence of widespread nudity and naughtiness could not make it interesting to watch.
