Two recreations of CSS "Texas" were constructed for the movie, a scale model and full sized exterior and interior sets, however their outer appearances did not correspond with what is known about the historical vessel; instead the vessel as represented in the movie resembled in outer appearance an amalgam of the original (of the Battle of Hampton Roads fame and Porter's original casemate ironclad (co-)design, on which he based his two basic, 150 ft and 180 ft, standard designs, "Columbia"-class being an enlarged variant of the latter) and the CSS "Tennessee" (the famed class sister), which were both endowed with substantially larger and differently shaped casemates, for reasons already explored above in the latter case.
