Why Did Thora Birch Leave ‘Wednesday’ and Is It Permanent?

Something else that deeply affected Thora was working with both Brittany Murphy and Brad Renfro, who both died young, Brittany from complications due to pneumonia, and Brad from a heroin overdose. Working with Brad on Ghost World, Thora said she felt devastated by how he looked, and wished she, “said something, like: isn’t there something that should be done, other than a guardian who is not a guardian…” What was more upsetting for her, was her lack of shock over both their deaths.
