Martin McDonagh's Three Billboards Outside Ebbing, Missouri triumphed at Sunday's Screen Actors Guild Awards, picking up three of the top awards.
Frances McDormand won the leading female actor award, Sam Rockwell picked up the supporting male actor gong and the film went on to win cast in a motion picture, closing out the ceremony.
McDormand thanked London-Irish director McDonagh as she accepted the award, saying: "When Martin wrote Three Billboards Outside Ebbing, Missouri he did not sketch a blueprint, he did not string together a few words.
"He wrote meticulously and crafted a tsunami. Then he allowed his troop of actors to surf it into the shore. Thank you, Martin."
The female actor in a supporting role gong went to former West Wing star Allison Janney for her performance in I, Tonya.
Nicole Kidman and Alexander Skarsgard were both honoured for their depiction of a married couple in an abusive relationship in Big Little Lies, picking up the outstanding performance by a female and male actor in TV movie or limited series respectively.
Speaking from the stage during the ceremony, Kidman said: "How wonderful it is that our careers can go beyond 40 years old.
"Twenty years ago we were pretty washed up by this stage in our lives.
"That is not the case now, we have proven that we are potent and powerful and viable."
Meanwhile, the captivating Claire Foy took home the award for outstanding performance by a female actor in a drama series for her portrayed of Queen Elizabeth II in The Crown, while Sterling K Brown blew away the competition to win the outstanding performance by a male actor in a drama prize for This Is Us.
This Is Us also took home the ensemble cast in a drama gong, with Veep taking the equivalent award for a comedy series. Its leading star Julia Louis-Dreyfus won the award for outstanding performance by a female actor in a comedy series, with William H Macy picking up the parallel award for his part in Shameless.
Morgan Freeman was honoured with a lifetime achievement award at the ceremony. It was presented to him by actress Rita Moreno, who previously received the same award from Freeman.
The 80-year-old actor thanked his family and business partner, before adding: "This is beyond an honour, this is a place in history."
