The longer version, titled Behind the Iron Mask, ends with a fadeout and no end credits at all. All of the film's credits are at the beginning.
In the longer version, titled Behind the Iron Mask, Sylvia Kristel, Beau Bridges and Ursula Andress are credited simultaneously (in this order). However, Bridges' name is positioned slightly higher on screen than the two ladies. This way it can appear that either Bridges is top billed (being the highest credit of the three) or Kristel (when reading from left to right). A similar construction was employed during the opening credits of Jaws (1975) for it's three leads.
