'Parasite' was the surprise winner of the Screen Actors Guild (SAG) Award for Outstanding Performance by a Cast in a Motion Picture.
The South Korean comedy-thriller made history as the first foreign language film to ever win the honour.
It's seen as a reliable indicator for the Best Picture Oscar winner - as it beat off competition from Bombshell, The Irishman, Jojo Rabbit and Once Upon a Time in Hollywood.
Other full cast honours went to The Crown for Outstanding Performance by an Ensemble in a Drama Series, while the comedy equivalent went to The Marvelous Mrs. Maisel.
Speaking on stage at Los Angeles' Shrine Auditorium, Alex Borstein admitted: "I voted for Fleabag. This is really weird. This makes no sense...Fleabag is brilliant."
The Marvelous Mrs. Maisel also scored a win for Tony Shalhoub in the Outstanding Performance by a Male Actor in a Comedy Series category, with the Outstanding Performance by a Female Actor in a Comedy Series honour going to Fleabag's Phoebe Waller-Bridge.
Joaquin Phoenix won Outstanding Performance by a Male Actor in a Leading Role for Joker and used his acceptance speech to sing the praises of his fellow nominees in the category, before acknowledging another star who had played the Joker, his "favourite actor", the late Heath Ledger.
"I'm standing here on the shoulders of my favourite actor, Heath Ledger, so thank you and goodnight," he said.
Outstanding Performance by a Female Actor in a Leading Role went to 'Judy' star Renee Zellweger, who dedicated the honour to the late Judy Garland.
Leonardo DiCaprio honoured Robert De Niro with a lifetime achievement award, and as well as praising the acting community, the 'Irishman' star also bemoaned the current "dire" political climate.
