Alex Wolff

Toni isn’t the only 'Hereditary' star to express distaste for horror as her co-star Alex Wolff said his role in Ari Aster's flick left with post-traumatic stress disorder (PTSD) as a result of the harrowing themes of the flick.

He recounted: "When I started talking about it, all these flashes with all this disturbing s*** I went through sort of came back in a flood.

"It kept me up at night, to where I got into a habit of emotional masochism to the point of just trying to take in every negative feeling I could draw from. I forced it upon myself rather than the opposite of what you’d usually do in life, which is sit on the heater until it starts to burn, and you jump up immediately.

"I had to do the exact opposite of that and absorb the pain and let it burn. It’s a reverse emotional thing.

"It’s hard to describe eloquently; it’s just a feeling. I don’t think you can go through something like this and not have some sort of PTSD afterward."
