He is the most sought-after man in Europe in the 1960s. Lex Barker embodies the flawless hero in his films and, as Old Shatterhand, becomes a role model for generations of fans. Revered in Europe, misunderstood and almost forgotten in his native America. But who was this American who rode through Yugoslavia in a leather costume for the European audience?
