March or Die is a movie well-worth watching. Actors include Gene Hackman, Terence Hill, Catherine Deneuve, Max von Sydow, Ian Holm (funny seeing a British actor as a Moor, but after seeing Sean Connery in The Wind and the Lion nothing surprises me), and some other good actors.
By the way, the IMDB mentions as filming locations just California and Morocco. However, I'm sure most of the SW fans will recognize in the movie the fortress built for El Condor (though in the movie its walls have a coat of brownish paint and it has been reworked to look Arabic), the dunes of te desert that Tuco forced Blondie to cross, and also the well-known railroad tracks around La Calahorra in Almeria (where Tuco jumped off the train in GBU and Henry Fonda confronted single-handed The Wild Bunch in My Name Is Nobody).
7 out of 10. 
I taped this off ITV4 a couple oy years ago and it's pretty good if a little downbeat.Terence Hill proves his worth as an action figure with his trademark acrobatics but not so much with the humour if i remember it correctly.
Since i last posted here i got I'M FOR THE HIPPOPOTAMUS which is one big tedious yawn from start to finish.

But WHO FINDS A TREASURE FINDS A FRIEND has grown on me with repeat viewings and the Moving,Moving,Moving theme song is real catchy.

One thing i haven't done so far which i intend to put right is to check out Bud Spencers FLATFOOT series where he plays a city cop who prefers fists to firearms.
