Despite being part of the Marvel Cinematic Universe, it turns out, Chadwick Boseman doesn't really know his Avengers costars as well as he thought. During his stop on The Ellen DeGeneres Show on Monday, the 41-year-old actor played a game of "Does Chadwick Boseman Knows Them?," where host Ellen read Chadwick a statement about his costars and he decided whether it was true or false. He got the first question about Scarlett Johansson correct, but it was all downhill from there. "You're losing this game," Ellen told him. "Go against your intuition!" Let's just hope Chris Hemsworth, Brie Larson, and Samuel L. Jackson don't watch this.
