As the 1930's ended, after small parts in over 50 Hollywood movies throughout the 1930s – Grable finally gained national attention on stage for her role in the Cole Porter Broadway hit Du Barry Was a Lady (1939).
Grable's later career was marked by feuds with studio heads. At one point, in the middle of a fight with Zanuck, she tore up her contract and stormed out of his office. By 1953, Zanuck was grooming Marilyn Monroe to replace Grable as the Fox's resident sex symbol. Far from feeling threatened, on the set of How to Marry a Millionaire Grable famously said to Monroe, "go and get yours, honey! I've had mine".
