Martin Sheen's portrayal of Gen. Robert E. Lee in Gettysburg was lame. Ted Turner might as well have used a cardboard cutout to duct-tape to the saddle of ol' Traveller. One who watches that movie can't help but think, every scene where he shows up, "that's not General Lee, that's Martin Sheen with a paste-on gray beard".
Turner did a much better casting job in Gods and Generals when he chose Robert Duvall to play Lee. Duvall was brilliant. Duvall WAS Lee. Sheen could take a lesson from that performance. Watching Gods And Generals, I actually had tears running down my cheeks when Gen. Jackson learned of the death of his "young friend"...and for me to get misty-eyed in a movie is very rare.
Martin Sheen was trying to do Shelby Foote’s accent, and failed miserably!
