"whilst Audrey Hepburn ran around Rome"

This refers to the 1953 romantic comedy film ‘Roman Holiday’, starring Audrey Hepburn as a princess exploring Rome. Directed by William Wyler, Hepburn plays a crown princess on a public tour of Europe.

The film was well-received and acclaimed with several Academy Awards, including one for Audrey Hepburn as Best Actress.
