A Train for Durango is a very enjoyable western comedy, a funny spoof about 2 losers who are not too bright and always ended up getting laid.
I always thought that Mario Caiano had quite an eye for westerns, but surprisingly this is his only one of greater interest so far (haven't seen all of him). It seems that all he needed were some better screenplays or basic ideas.
But the real surprise is a very convincing Anthony Steffen, the best I have seen from him as actor (his best film is still Django the Bastard). In Ringo: Face of Revenge he played a similar role, but unfortunately the film changes his style after half of it's length, film and actor became a typical (and boring) revenger and Steffen fell back to Stiffen.
Luckily Caiano and Steffen stayed for A Train for Durango to their concept, to which Duccio Tessari contributed as screenplay writer.
