This was a fantastic interview and I can see why this all over the place right now. Keanu Reeves has always struck me (and lots of people) as a humble, kind kind of person. He joined in on the Late Show with Stephen Colbert to promote John Wick 3, but also discussed the upcoming Bill and Ted sequel. Colbert hit Reeves with a deep question in there too: "What happens when we die?" Check out the pretty lovely answer in the clip.
Hint: it's people missing us, in case you don't wanna watch. It's a great interview, though, so I would watch the whole thing if you're a fan of Keanu Reeves.
