Zoolander 2. I found out from easyfrascati friend, local food coach and blogger Jo Donghi of https://frascaticookingthatsamore.wordpress.com/ fame :
"Some scenes were filmed in Frascati, at the gorgeous Villa Aldobrandini. And since he was in Frascati, Ben Stiller thought it would be a good idea to dine chez Cacciani. Here he is sitting next to Paolo Cacciani. After WWII when the Italian Film Industry took off and Cinecittà II Film Studios were at their height, their proximity to Frascati and the Castelli Romani meant that many actors came to stay here. Richard Burton and Elizabeth Taylor, to mention just one couple. Orson Wells rented a house not far from Monteporzio. Fellini's favorite restaurant was the Il Fico Vecchio, at Grottaferrata. And Swedish actress Anita Ekberg, famed for her show stopping scene in the Trevi Fountain in La Dolce Vita ...well, she even chose to end her days here. She died near Ariccia only last year. Villa Aldobrandini was used also for some scenes in the films Portrait of a Lady and Lady Caroline Lamb."
We'll dedicate a Humans of Frascati page to her too soon!
