In Thor: Love and Thunder, when describing Thor's love life, Korrg explains how Thor fell in love with a "swashbuckling pirate" among others. The pirate was played by Elsa Pataky, Chris Hemsworth's wife. Has there ever been other instances of this in other Marvel movies, specifically where a lead actor's spouse or significant other has played another role in the movie? Any Marvel-produced movie or show, MCU or not, is acceptable.
Note: I'd not accept the Tom Holland Spider-Man movies in the case of Tom Holland and Zendaya, who became a couple after Spider-Man: Homecoming was released.
