Peter Wyngarde was originally tested for the lead role of Alexander, but ended up in the smaller role of Pausanias.

Helmut Dantine's role is dubbed by Christopher Lee (uncredited).

Charlton Heston turned down the title role, adding "Alexander is the easiest kind of picture to make badly".

Although Richard Burton was only 29 at the time of filming, many critics felt he already looked too old to play Alexander.

Average Shot Length (ASL) = 7 seconds (135 minute version)

Rossen shot the film to run three hours plus an intermission and was very disappointed when the producers cut it to 141 minutes.

The first film of Peter Wyngarde.
