Wow. Truly one of the most remarkable careers in Hollywood. There are so many under seen gems in his catalog, and two that really are worth seeking out are Tomorrow (1972) and Convicts, which were both written by Horton Foote, who collaborated with him on Tender Mercies and To Kill a Mockingbird as well (I thought they were distant relatives, too)
Lonesome Dove doesn’t hold up as well as I thought it might, but it was one of the last major event miniseries for American network television, and he’s perfect in it
