At 78, John Lithgow's acting career is not slowing down. He appeared in the best picture nominee “Killers of the Flower Moon” and starred with Jeff Bridges in the FX series “The Old Man." Recently, the two-time Academy Award nominee and multiple Emmy, Tony and Golden Globes-winning actor played the new kid in school. He learned dance, ceramics, silk-screen printing and vocal jazz ensemble with Los Angeles-area high school students. It was filmed for “Art Happens Here with John Lithgow,” airing Friday on PBS with the goal of promoting arts education.
