The two descendants of Hollywood royalty (Coppola is a grandchild of Francis Ford and Hawke is the first-born of Uma Thurman and Ethan Hawke) said they have been tested repeatedly for the virus since arriving, as required by festival organizers for participants from outside Europe.

"It feels like a moment where we're like 'OK, we can follow the rules and we can still celebrate art and filmmaking and protect each other, keep each other safe,'" Hawke said, adding that she appreciated in particular the discipline of festival-goers in adhering to Italy's anti-virus precautions that include mask mandates and social distancing norms.

In the U.S., "we're still really struggling and having trouble working together. And that's what feels so good about being here: that everyone is working together really, really well and respecting each other," she told The Associated Press on Saturday.

It's Coppola's second feature-length film and second appearance at Venice, after her 2013 debut "Palo Alto," competed in the Horizons section for up-and-coming talent, where "Mainstream" is also making its debut.
