From Natasha Romanoff reuniting with her sister in Black Widow to Wanda Maximoff trying to protect her sons from the truth in WandaVision, family is a pretty important theme in a lot of Marvel movies.
In the MCU, the importance of family stretches behind the scenes. Some relatives work as a team to help bring our favorite superheroes to life, and others help each other land an enviable cameo role.
Here are 29 pairs of relatives who've worked in the MCU:
1. Chris Hemsworth plays Thor in Thor: Love and Thunder.
His daughter India Hemsworth plays Gorr's daugher.
During a roundtable interview with Entertainment Weekly, Christian Bale, who plays Gorr, told Chris, "She was so magnificent in it. But it was also so cute seeing your relationship, and her having to be like, 'Who's this weird bald bloke who's all covered in scars and crying over [me]?' [I saw] what a good dad you are, gently coaxing her through it, like, 'No, just stay there. I know he's a bit disgusting, but just stay there.'"
They shared the role of young Thor during the transitional sequence in which he gets older as he runs through the woods.
3. Natalie Portman plays Dr. Jane Foster / Mighty Thor.
Her children, Amalia and Aleph Portman-Millepied, cameo in the film.
4. Christian Bale plays Gorr.
His children, Emmeline and Joseph Bale, cameo in the movie as well.
5. Taika Waititi serves as both director and the voice of Korg.
His children, Matewa Kiritapu and Te Hinekāhu, helped design the shadow demons that Gorr summons. They also cameo in the film.
Waititi told Marvel.com, "My daughter was watching me write the script one day and she looked over my shoulder and says, 'What's a shadow demon?' I was like, 'I don't know.' And she goes, 'What does it look like?' So she went and drew one...And I gave it to the Visual Development department, and they turned it into a fully rendered monster."
He continued, "Then I just started asking everyone else around the office. I was like, get your kids to draw some monsters. And then we just had a collection of monsters. So all of those monsters that Gorr summons, the reason they look so crazy is because they're all designed by children."
