The new DVD extra isn’t really a blooper reel, since any of McKinnon’s lines could work in the movie. It’s more of a testament to her incredible improvisational powers, coming up with multiple analogies for boinking Chris Hemsworth. For example: “He’s like a Christmas napkin. Nice to look at, then you wipe it across your mouth, throw it in the trash and never think about it again.”
It’s almost like you’re watching Ghostbusters 2, but with all the boring extraneous characters, like the men, edited out.
