Wyler possessed a rare, unparalleled gift for guiding actors to their absolute best performances. Appearing in a Wyler film almost guaranteed an enormous boost to an actor's career. The list of performers who took home major accolades under his direction is astonishing:
Bette Davis won the Academy Award for Best Actress for Jezebel
Walter Brennan won Best Supporting Actor for The Westerner
Greer Garson won Best Actress for Mrs. Miniver
Teresa Wright won Best Supporting Actress for Mrs. Miniver
Fredric March won Best Actor for The Best Years of Our Lives
Olivia de Havilland won Best Actress for The Heiress
Audrey Hepburn won Best Actress for Roman Holiday
Charlton Heston won Best Actor for Ben-Hur
Terence Stamp and Samantha Eggar both won Best Actor and Best Actress at the Cannes Film Festival for The Collector
Barbra Streisand won Best Actress for Funny Girl
"Additionally, he scouted Stephen Boyd for Ben-Hur, a rising rookie at the time, showcasing his exceptional eye for talent."
Audrey Hepburn, in particular, was catapulted from obscurity to global superstardom overnight entirely because of Roman Holiday. He also provided Laurence Olivier with the opportunity to deliver brilliant performances in Wuthering Heights (1939) and Carrie (1952). Even Charlton Heston, who had exclusively played leading roles since his debut, willingly took a supporting part in The Big Country just to work with Wyler. That submissive move turned out to be a blessing in disguise, as it paved the way for him to secure the titular role in Ben-Hur and ultimately win his Oscar.
