Harrison Chants at Mad Stabber; Lange’s Acid-Tongued Belle: TV

When a knife-wielding madman broke into George Harrison’s country mansion in 1999, the spiritual Beatle who melded sitar with psychedelia responded with a chant.

That small, strange detail is recounted almost offhandedly by George’s widow, Olivia, in Martin Scorsese’s affectionate, exhaustive two-part HBO documentary “George Harrison: Living in the Material World.” Harrison’s easily mocked mysticism has rarely seemed as sincere and hard-won as it does in Scorsese’s respectful, 3 1/2-hour profile.
