Nicole Kidman's appearance in Bombshell is noticeably different than her typical look. In the film, she wears a blonde wig and has heavy makeup, which gives her a completely different appearance. While some might think that this was done for dramatic effect, it's actually based on real life. Kidman wore a wig and had heavy makeup in the film because she was playing Gretchen Carlson, a Fox News anchor who was fired from the network after alleging sexual harassment by then-CEO Roger Ailes.
