To longtime Keanu-philes, he’s always been The One. Suddenly, though, the whole world’s gaga for Keanu Reeves. He’s having a hell of a year: “John Wick: Chapter 3” arrived to rave reviews, he hilariously sent up his spacey image in Netflix’s “Always Be My Maybe,” and he pops in as a Pixar daredevil in “Toy Story 4.” At 54, he’s the new face of Saint Laurent, dashing in Wick-esque dark suits. He’s now shooting a third “Bill & Ted” installment. There’s a petition to make him Time magazine’s Person of the Year.
