Mad Max: Fury Road star Charlize Theron was demonstrating her super hero like stamina during another day of promotions for her new movie.<br /> The blonde beauty, who plays Furiosa in the reimagining of the 1979 classic, was up bright and early for an appearance on Good Morning America.<br /> Despite the early start the South African stunner showed off her serious style credentials in a summery Isabel Marrant printed mini dress. The floaty number perfectly complimented Charlize's model figure showing off her long lean legs, which she accentuated with a pair of grey suede booties.
