A decade ago, actress Lulu Wilson (who had previously worked with filmmaker Scott Derrickson on Deliver Us from Evil) found herself joining the Marvel Cinematic Universe as Doctor Strange's Donna Strange.
In a flashback, we'd have learned that Stephen Strange's younger sister died in an accident when the siblings were playing on a frozen lake. When that cracked, she drowned, with Stephen unable to save her. As a result, he was inspired to become a doctor in order to save lives, and Marvel Studios even considered revisiting this crucial piece of backstory when Nightmare was set to be the sequel's main villain.
Derrickson has previously revealed that the emotional sequence was cut because it didn't fit Doctor Strange's narrative, and while he shared his hopes at the time for it to be released as a deleted scene, that's never happened.
Talking to ComicBook.com. Wilson said she'd love to reprise the role if the opportunity presents itself (which is doubtful given her age) and reflected on the experience.
"On that one, I was in fifth grade and was really, really young. It was just a couple of days of me on set and I'm not going to say what I did," she recalls. "I died and that's the whole thing because Donna Strange is dead and Doctor Strange is like, 'My sister is dead!'"
"So I died and remember being a little bit pissed because come on, that would have been a good moment and would have been good for me."
Doctor Strange in the Multiverse of Madness referenced Donna's death, and it definitely feels like the door could be open to revisiting the hero's childhood in the not-too-distant future. Whether that will happen remains to be seen, but it's easy enough to understand why Wilson is so disappointed to have never seen her scenes!
Doctor Strange 3 is rumoured to be in development but doesn't have a confirmed release date.
