Now it seems the upcoming Thor: The Dark World will be reshooting a few things as star Kat Dennings confirmed with IGN that the film is going back in front of cameras. This is happens all the time and should not ring the fire bells in anyone’s head.
Dennings wouldn’t specifiy exactly what was being reshot, but star Jaimie Alexander, who plays the warrior Sif, has also spoken about doing reshoots. It remains to be seen if Dennings’ Darcy Lewis will meet up with Alexander’s Sif, but anything is possible.
