The post-credits scenes for Marvel Studios’ Thor: Ragnarok were included in the film’s reshoot schedule.
As such, it didn’t come as much of a surprise when it was revealed that Marvel had begun multiple weeks of reshoots for Thor: Ragnarok in Atlanta, earlier this month.
Not only is Thor: Ragnarok the second-to-last film before Avengers: Infinity War, but the reshoots for Ragnarok took place in Atlanta at the same time that Infinity War was wrapping production.
There’s two characters in the film that potentially have a fight scene, and some of the reshoots were just adding.
