How often do we get an ACW film in theatres?

Major Dundee has been in cinemas since April 8.
In this re-release of Sam Peckinpah's 1965 film, a Union officer is assigned the task of assembling a hunting party after a New Mexico settlement is massacred by a band of renegade Apaches. But with the Civil War still raging, he must fill out his ranks with Confederate prisoners, freed slaves, deserters and criminals. As the mission progresses, he must guard against not only both his quarry and his recruits, but his own personal demons as well. Starring Charlton Heston, Richard Harris, Jim Hutton, James Coburn, Michael Anderson Jr., Senta Berger, Mario Adorf, and Brock Peters
A 94% positive rating resides at Rotten Tomatoes. Lots of raves here, too: "a near masterpiece," "Greatest western/civil war drama of all time."

Consider: "Heston was so committed to the director's vision that when the studio shortened the production schedule, he actually forfeited his entire salary to buy back the extra days Peckinpah needed to finish shooting."

Am quite looking forward to this. Have a good weekend.
