LOS ANGELES—During an hour-long chat at his Los Angeles home, Henry Winkler does impressions of George Foreman, Terry Bradshaw and William Shatner (his co-stars in the new NBC reality series “Better Late Than Never”), walks like a ninja who suddenly sports jazz hands, and improvises a scene as the intolerant acting coach he plays in a new HBO comedy.
The 70-year-old entertainer is visibly animated as he discusses his career, which spans four decades and counting. But the overriding vibe from the former Fonz is one of gratitude. It’s not long before he launches into how thankful he is for the opportunities and success he continues to enjoy.
