Gillian Anderson & David Duchovny – The X-Files

Fans hate hearing about this feud, but indeed Mulder and Scully were extremely hostile to each other on set, with Anderson once stating that “familiarity breeds contempt.” Yet, it was more than just getting sick of each other that got between these two. Duchovny was paid twice as much as Anderson, plus she was always made to walk behind him in scenes. These facts stood, despite having equal billing and dialogue, because Anderson was a woman. Wow. Surprised they were able to pull off any chemistry at all.
