‘Mad Max’ stars Charlize Theron, Tom Hardy had heated exchange during ‘Fury Road’ filming: ‘How disrespectful'

In “Blood, Sweat & Chrome,” a book that sheds light on the film that grossed nearly $375 million in worldwide box office, Theron, 46, explains the brother-sister dynamic she shared with Hardy and ultimately says the rift between the two A-list performers shouldn’t have spilled into production in the myriad of ways they allowed it to.

"It was like two parents in the front of the car. We were either fighting or we were icing each other — I don’t know which one is worse — and they had to deal with it in the back. It was horrible! We should not have done that; we should have been better. I can own up to that," she explains in an excerpt, according to Vanity Fair.

However, on-set crew members further revealed the jaw-dropping incident that allegedly sent Theron over the edge after Hardy, 44, arrived to film some three hours late while she had sat waiting for the "Dark Knight Rises" star in the War Rig while in full costume — makeup and all.
