Terrifier 3 director says the movie's most hilarious moment that everyone is loving was actually improvised

Terrifier 3 is shocking moviegoers around the globe with its brutal kills and simply barbaric finale. But one of the best horror movies of the year’s last showdown is lightened by a hilarious moment that fans cannot get over, which director Damien Leone says was actually improvised.

Warning, the following article contains spoilers for Terrifier 3 , so make sure to watch the film before reading on. But before you head to theaters, read our verdict on the new horror film in our Terrifier 3 review .

At the end of the movie, Art the Clown (David Howard Thornton) has final girl Sienna (Lauren LaVera) tied up to a chair, forcing her to watch himself and the demonically possessed Victoria hurt her aunt. But the disturbing scene is making fans laugh out loud in theaters as in between conducting medieval torture methods, he keeps comically slapping her on the back of the head.

However, as funny as it may be, Leone says it was completely improvised. "This was something I spontaneously told David to do on set every time he passed Lauren because I felt the finale was too dark and we needed some levity," said Leone via Twitter . "Glad we share the same twisted sense of humor." See the full post below.

Well, it looks like that last-minute addition of comic relief worked as fans cannot get enough and have been reacting to the scene on Twitter since the movie dropped on October 11. "THAT SLAP WAS TOO FUNNY LMAO," said one fan , another added, "got my whole theater hollering when he kept doing that." See more reactions below.

The third installment swaps Art the Clown’s usual reign of terror on Halloween night for the Christmas period as the clown suits up as Santa Claus and wreaks havoc on Miles County once again. Alongside LaVera and Howard Thornton, returning cast members include Samantha Scaffidi as Victoria and Elliot Fulham as Jonathan Shaw.
