Not post-screening, but at opening night of Avengers: Endgame. Packed theatre, luckily a very respectful crowd. At the part where Ant-Man gets out of the quantum realm and has no idea what is going on, he visits that memorial with all the names of people who got snapped, and the dramatic shot of him finding his own name....in the dead silence the dude next to me leaned over to his partner and said, "Who's Scott Lang?"

Marvel movies can be a nightmare if you're a casual viewer so I hope he wasn't too confused for the rest of the movie.
