Stephen Colbert was joined by Ryan Gosling and Russell Crowe on the Late Show last night, where they talked about The Nice Guys and their newly-forged friendship. It wasn’t all pleasantries, though, as Gosling and Crowe playfully bickered a bit. Then Gosling threw down the Lord Of The Rings gauntlet, on behalf of his mother. Apparently, Mother Gosling was not a fan of The Colbert Report persona, but came around to the late-night host when she realized they shared a love of J.R.R. Tolkien. So she sent a question via Gosling, which left the avowed Tolkien nerd speechless.
