Hollywood stars and moguls meeting and performing for dictators isn't a new thing. The first ones to do so were this acting power couple, considered to be the first of such, and cofounders of a movie studio wined and dined with Mussolini pre WWII.
Among the others:
1. The newspaper magnate and his actress mistress/possible wife dined with Hitler and Joseph Goebbels.
2. That comedy producer/mogul whose films still get played on TV had a signed picture of Mussolini in his office . He even brought two of his biggest stars who are the subject of a recent biopic for a photo op. A deal with the Cinecitta Studios, then under fascist control, eventually fell through.
3. It has been debated whether that mogul whose last name and creations you see everywhere met with Mussolini for a photo op! but most evidence points to yes, he did. But he did not support fascism, as many people want you to believe
4. This A++ list Oscar winning director, who many people forget is foreign born, met with Mussolini numerous times and had a big oil painting commissioned of Il Duce to hang on the wall of his living room. That painting mysteriously disappeared once the US entered WWII and the director went on to direct propaganda films for the US government.
5. This mogul badly wanted to meet Mussolini and Hitler, but he did get a visit at his studio from Mussolini's son Vittorio who did a photo op with the mogul and his biggest star of the studio's first decade. Vittorio was also friends with #2 and #3
