Yep, he was a professional actor and, like all of them, took some clunker roles to keep working and food on the table.
Here is another one of those, 1974's "Zardoz"! I think that he would have preferred the kilt here! One year later he starred in "The Wind and the Lion" AND "The Man who would be King"!
Yeah not a fan of zardoz. Big fan of the Wind and etc John Milieu flick. Great screen writer and director.
