March or Die (1977)

Even Gene Hackman can have a bad day, and this was it. As the commander of a Foreign Legion outpost, fighting a battle he doesn’t believe in, his men are massacred by Spanish extras posing as Berbers.

These things happen.

Almeria once more provides perfect Saharan scenery, and the Alcazaba features in the scenes when the archaeologist MaxVon Sydow locates the treasure, supposedly at Erfoud in Morroco, and occasional views of the walls around the castle are plastered sneakily onto the fort scenes too.
