The actor discussed the topic during a recent Hot Ones interview, a format that sees celebrities answering questions while food coated in increasingly spicy sauce.
He was asked about a fan theory that became particularly popular in the lead-up to Avengers: Endgame‘s release in April 2019.
Ant-Man, who is portrayed by Rudd in the Marvel Cinematic Universe, has the power to shrink to sub-microscopic size and to expand to giant proportions.
Fans thus started floating the theory that the superhero could, technically, shrink down and crawl up Thanos’s bottom before becoming a giant – thus defeating the genocidal villain.
“What do you make of the ‘Ant-Man kills Thanos by crawling up his butt’ meme?” asked interviewer Sean Evans.
Rudd let out a deep sign before responding: “I consider it a lost opportunity.”
The actor’s jokingly serious tone was met with laughs from Evans.
