The Simple Life of Noah Dearborn (1999)

Sitting on 35 acres of Georgia land coveted by a shopping mall developer, 90+years-old Noah Dearborn is untainted by modern life. He's never heard of the Beatles, and his only interest is his woodworking, in which he excels. The girlfriend of one of the developers is a psychologist, and is asked to evaluate Noah for a possible move to have him declared incompetent. But she soon falls under his spell of a simple life and becomes his ally in his fight to keep his land.
