Finn, who makes his directorial debut withSmile, chatted with Entertainment Weekly back in September about Paramount Pictures placing performers at baseball games and instructing them to smile as widely as they could, to promote the film.

Thestunt went viral, with Finn telling EW of the studio’s “clever” marketing, “This is something that had been discussed a little while back and we were all kind of like crossing our fingers that somebody might notice.”

Of the film itself, Finn told the outlet, “I wanted to set out to make something that was deeply frightening andfeels like a sustained panic attackfrom start to finish.”

“We’re working with really heady themes and motifs and pairing them with these extraordinary circumstances,” the director continued. “I really wanted to ground the story, the drama side of things, so [the audience] can really care about the character and go with her on that journey when it all really really starts to ramp up.”

The film debuted at No. 1 at the domestic box office during its opening weekend,bringing in more than $22 millionbetween Sept. 30 and Oct. 2.

Sosie, 30, is the daughter of actors Kyra Sedgwick andKevin Bacon— the latter of whom also had a horror movie out this year, the Peacock OriginalThey/Them.

TheGolden Globewinner, 64, opened up toThe Hollywood Reporterlast month aboutwhat it was like to see Sosie inSmile— and, as he explained, it’s a family thing.

“When she got this part, even knowing how hard she had worked, and knowing she was good, when I saw the movie I was just really taken aback not only with how great she was but also how hard that role was, because it’s one of those parts where there is no break,” Kevin shared.

He added of their shared genre experience, “In a weird kind of way, we havea horror tradition in our family. One of my earliest movies was the very firstFriday the 13th. I was inStir of EchoesandHollow Man.Flatliners. I keep going back to horror.”

Smileis in theaters now.
