BEVERLY HILLS, Calif. — “The best things that ever happened to me happened when I was in Boston,” Carl Reiner says.

That’s Reiner’s style — humorous and light, with an easy charm. Greeting a Boston visitor to his home, he radiates warmth, sitting in his favorite chair in the cozy living room. He’s dressed in a blue suit jacket and tie, but black sneakers, waiting for his ride to “Jimmy Kimmel Live,” when he launches into a story.
