Ben Affleck definitely noticed Casey did not thank him in Golden Globes speech

Oh brother.

When Casey Affleck took home the Golden Globe for best actor in a drama, he thanked a lot of people. But he did not thank one person in particular. And that person was his brother Ben Affleck.

When you're a famous actor and director and you happen to be promoting your latest movie (Live By Night) on a late night talk show, instead of privately ribbing your brother for the snub, you get to do it very, very publicly.

While stopping by Jimmy Kimmel Live, Ben and the host spent the better part of a segment burning Casey, bringing up the fact that Ben thanked his brother in his Oscar acceptance speech for Good Will Hunting back in the day, and listing some embarrassing "facts" about Casey.

If he takes home any more awards this season, Casey might do well to thank his big brother.
