Ryan Gosling was on The Late Show Thursday with Russell Crowe to promote their new movie The Nice Guys. They took a brief break from the regular late night interview to talk about Gosling's dear mother. It turns out she was very much not a fan of Colbert's former comedic persona on The Colbert Report. As is the case with moms, she disliked the real Colbert because she associated him with a fake character he played on TV. But then she learned she had something in common with Colbert: they're both Lord of the Rings nerds.
