If you’ve seen “The Uninvited,” you know that it’s one of those intense, mind-tripping horror thrillers best viewed by those who know nothing about it. And you also know that when it came down to what could be revealed and hidden in each scene, stars Emily Browning and Arielle Kebbel needed to be very…um…precious.

“I knew there was some kind of twist coming, but I wasn’t sure how they were going to be able to carry it off in the American version,” Browning recently told us of her creepy remake of the South Korean film “A Tale of Two Sisters,” now on DVD. “It made it tricky, because it felt like we were filming two different movies. There was what the audience thought, and what was actually going on.”

We’ve all seen movies with great twists (“The Sixth Sense,” “Fight Club,” “The Others”) and movies with really bad ones (“Stay,” “Basic,” “The Number 23”), and Browning said that the difference between the two is often just a matter of execution. “You want the film’s twist to be believable enough that people can go back, watch the film again and go ‘Oh, I see what’s happening there.’ It’s tricky to try and do both of those things at the same time.”

It was also tricky to work on the day when the script called for Browning’s boyfriend in the film to descend into a physical malformation — requiring a stuntman practiced in the arts of contortionism.

“On that day, there was a contortionist; so all those shots you see of him coming towards me, I was freaked out,” laughed the actress, who has a special place in the hearts of “Twilight” fans as the Bella Swan that never was. “This guy could do this thing where he’d move his heart in his stomach [and you could see it]; it was terrifying.”

Luckily, in order to help create a great movie twist, Browning was willing to watch some painful twisting by her flexible co-star.
