Though Anthony Mackie was busy in 2019 fighting Thanos in Avengers: Endgame, he also appeared in an episode of the hit sci-fi series Black Mirror that same year, portraying a man who reconnects with his best friend through a virtual reality fighting game. Mackie is set to take up the shield of Captain America next, but before we get there, he recently shared what happened to a “nerdy kid” while he was shooting his episode of Charlie Brookers series in San Paulo, Brazil.
