10 Horror Movie Scenes That Genuinely Terrified Actors

10. Meeting Pennywise - IT

By today's standards, Tim Curry's depiction of Pennywise in the IT mini-series seems hammier than a pig farm. (That goes double if you compare his work to Bill Skarsgard's tour-de-force performance in the IT remake.)

As hard as it is to believe for some, Curry's Pennywise is responsible for making an entire generation of kids pissing themselves anytime they see a storm drain.

But it wasn't just viewers who were creeped out by the child-eating clown, but the main cast. In-between takes, Curry scared the younger actors at any opportunity, (either to help them to stay in character or because he thought it was funny). Sometimes, he wore his fanged prosthetics, and bared his teeth to anyone who dared approach him.

Even though Curry's methods made the children's reactions more legitimate, it created some problems. While performing the iconic opening scene, Tony Dakota, who played Georgie, completely broke character. When Curry said his infamous line, "They'll all float," Dakota yelled, "Tim, you're scaring me!" Curry tried to reassure Dakota, reminding him that he was being paid to scare the hell out of kids.
