It doesn’t appear as if Grant, a three part History Channel presentation from exec producer Leonardo DiCaprio and biographer-historian Ron Chernow about the legendary Civil War general and U.S. President, can be called a “pure” documentary. The trailer suggests a reenactment drama mixed with a talking-head doc.

Directed by Malcolm Venville (Henry’s Crime), Grant is premiering on the History Channel beginning Monday, 5.25, or on Memorial Day. The usual 5.30 date has been moved up five days because 5.30 falls on a Saturday. Yeah, I know — why not have the holiday on Friday, 5.29?
