Several of the stars in the Marvel Cinematic Universe have had issues with remembering that they've worked together before.

Gwyneth Paltrow was recently called out by both "Spider-Man" star Tom Holland and actor Sebastian Stan (who plays Bucky/Winter Soldier) for not remembering them. But even Mark Ruffalo forgot that he was in the movie "13 Going on 30" with Brie Larson years ago.

The truth is that many of the stars have been in films together outside of the MCU. Some of those films were released way before their Marvel debut, so it's understandable why they might forget.

Here are 32 times the actors have appeared in the same projects. Marvel stars, you're welcome.
