"There was nothing small about her ego," her brother Robert says in a documentary about the actress. He says it laughingly and lovingly: after all, in the 1930s it was not common for a woman to present herself like that. She preferred to wear trousers, had no desire to have children and demanded a weekly rate of $ 1500 for her first film role - a pretty generous sum for a then unknown 25-year-old actress. And she got her way too.
This success however did not mean that she then just slipped through the cracks everywhere. In fact, her strong character sometimes actually worked against her. Katharine was different: she was independent, eccentric, tenacious, tough. This caused her to be fired regularly because others found her impossible. Yet she continued to fight for her roles. She had to and would become an actress, or even better: a star. That is why, with the help of a rich lover, she bought the film rights of a successful play and subsequently played a leading role in it. Moreover, she was hardly dependent on men. She married young, divorced six years later, did not marry anymore, but had an affair for 26 years with married actor Spencer Tracy.
