In 1928, although aged only 18 (the legal age of adulthood in the UK at that time was 21) she persuaded her parents to allow her to leave for Hollywood. She arrived in 1929 and was signed by
Fox Studios as a contract player and immediately began to obtain film roles. She was renamed Patricia (almost immediately shortened to Pat) Paterson, as the Pat-Paterson sound had an ear-catching alliterative rhythm. From 1930 to 1934 she appeared in many studio pictures, in roles of increasing prominence. In the 1935
20th Century Fox film
Charlie Chan Goes To Egypt, starring
Warner Oland as Chan, she played the female lead, Carol Arnold. This was intended by the studio to serve as her break-out role for leading parts. In early 1934, as production on
Charlie Chan Goes To Egypt was wrapping,
Maurice Chevalier persuaded his lifelong best friend, fellow French actor
Charles Boyer, to attend a Fox Studios post-New Year dinner party at which Pat Paterson was a guest. In interviews over the years, Boyer declared their meeting to have been a case of love at first sight. They married within four weeks of the party, on
St. Valentine's Day, 14 February 1934, in
Yuma, Arizona. ==Later Hollywood career==
