The Robe (1953)

This was the first movie to be released in Cinemascope.  And that is the best thing it has going for it.  A Roman General pisses of a not-yet-emperor Caligula by buying the slave he wants.  He gets sent to Jerusalem as punishment and takes part in the crucifixion.  He wins Jesus' robe, but when he puts it on he goes crazy.  A surprisingly accommodating Emperor Tiberius sends him on a mission to recover the robe (his slave ran off with it in Jerusalem) and destroy it to break the curse.  Eventually he becomes Christian and gets martyred with his wife, although it looks in the movie like Caligula declared them martyred, and then they ascended bodily to heaven.
