Several indirect references to old west style 'easy virtue' . One scene where the main characters go upstairs and roll around a bit with the brothel girls. About what you'd see in a PG-13 movie these days.
Man on fire. Shooting with blood at close range. Minimally provoked 'old west' violence and bar fights. Sword-play. Stabbing with a long sword.Many bloody gunshots, nearly all at close range, many in slow motion. Lots of blood pours from the wounds.
None.
Drinking in the bar scenes, on the airplane, etc. Some smoking. No drugs.
Operating on the robots is interesting and little intense when the pull the 'face' off the Gunslinger. The swordfights and gun battles are fairly intense even by todays standards. Rattlesnake attack.The final sequence is suspenseful and often frightening.
