Joachim Trier and star Renate Reinsve‘s Sentimental Value smashed past this year’s record for the longest standing ovation at Cannes on Wednesday evening,

The premiere crowd applauding the “Worst Person in the World” reunion for 15 minutes, clapping past the late hour of 1 a.m.

Elle Fanning, who plays a Hollywood starlet in the feature, wiped away tears and embraced Trier as the crowd whooped and hollered for her performance. Her co-star Stellan Skarsgård could be seen blowing a kiss to the crowd.

The intense reception sparked instant speculation that Trier’s feature could emerge as the frontrunner to win the Palme d’Or.

Though “Sentimental Value” is at its heart a family drama, Trier found several ways to poke fun at the film biz through its meta plot. At one point in the story, a film is acquired by Netflix and Skarsgård’s character is made to do a junket interview with a journalist, who brings up a past box office flop from Fanning’s character’s career. “Get out,” Skarsgard replies.

“Sentimental Value” follows sisters Nora and Agnes as they “reunite with their estranged father, the charismatic Gustav, a once-renowned director who offers stage actress Nora a role in what he hopes will be his comeback film,” according to the film’s synopsis. “When Nora turns it down, she soon discovers he has given her part to an eager young Hollywood star. Suddenly, the two sisters must navigate their complicated relationship with their father — and deal with an American star dropped right into the middle of their complex family dynamics.”

Along with Reinsve, Trier and Skarsgård, the “Sentimental Value” cast is rounded out by Cory Michael Smith and Inga Ibsdotter Lilleaas.

Trier penned the script with his frequent collaborator Eskil Vogt.
