Benedict Cumberbatch is totally enthralled by Matt Damon. They two have never met, but Benedict was more than willing to gush about Matt in a 2013 interview with Vulture:
"Well, he's just so grounded. He's so intelligent. He makes these smart choices, as an actor, as a producer, as a writer. He's so composed. You never hear a bad word said about him. Everybody loves him. And he just sounds like he's got his priorities right as a human being, and as an actor, he's phenomenal."
