It wasn't my type of (spaghetti) western either
I thought Crenna wasn't bad, tho'
I must have said this before: the story about this amnesiac gunslinger reminded me of Ludlum's first Bourne novel, The Bourne Identity
I have never read the Louis L'Amour novel this film was based upon, so I can't compare Ludlum's novel with his; it seems more likely that Ludlum saw this movie and was intrigued by these story elements about amnesia
Anyway, I have never heard that Ludlum had legal problems with L'Amour's heirs or Collinson, which surprises me
I think the story, original or not, was quite interesting, but not enough was done with it
Some good action scenes, but there are too much dust and slamming doors etc. in order to give the film an 'artistic' look.
