Charm is such an interesting quality – so hard to define objectively and so hard to fake. And this film is teeming with it. The screenplay was by Dalton Trumbo, then the subject of the HUAC witch hunt and written pseudonymously (Ian McLellan Hunter fronted for him and Trumbo’s credit wasn’t restored until 2003 on the dvd edition while the Writers’ Guild restored it in 2011) with John Dighton getting a co-writing credit. Director/Producer William Wyler wanted Cary Grant originally but he claimed he was too old – he would later be paired with Audrey Hepburn in Charade. In fact he probably saw that the role of the princess was the Real McCoy and would leave him in the shade. Elizabeth Taylor and Jean Simmons proving unavailable (whew), Hepburn won her first major role on the strength of a screen test when they left the camera running and she talked about herself. Royal stories were au courant thanks to the coronation of Elizabeth II so the fable of a beautiful girl going incognito in Rome and having a day out in the company of a charming (and equally undercover) journalist, played by Gregory Peck, couldn’t have been better timed. The fact that Trumbo was writing in the circumstances of a man trapped by his own profession adds piquancy to this story of duty, responsibility and the desire for freedom. Peck knew what Grant knew – Hepburn was a star – and midway through the shoot did what only a gentleman would do, something unheard of, and asked Wyler to give the beguiling Hepburn equal billing. She is luminous in the role and they exchange looks that suggest something beyond pure characterisation – feeling. Everything looks wonderful and I’m pretty sure hundreds of thousands of people visited the city on the basis of this movie alone. Post-war Rome was having a moment, and what is perhaps most astonishing about this was the decision to shoot in monochrome. What were they thinking?! There’s a notable score by Georges Auric and it is flawlessly made at a time when the city was becoming known as Hollywood on the Tiber. Charm itself.
