In December 1945, one month after returning from service in the Second World War, Andrews appeared with the Old Vic company at what was then referred to as the New Theatre, succeeding George Curzon in the parts of Sir Walter Blunt in "Henry IV, Part 1", Scroop in "Henry IV, Part 2", Creon in "Oedipus" and Sneer in "The Critic". The company toured to New York City in the summer of 1946, appearing at such venues as the Century Theatre. Upon returning to Britain in September 1946, Andrews continued performing with the Old Vic company through the end of the 1948–1949 season.
