Before she was a real housewife, Kyle Richards was in one of the most successful horror films of all time!

"The Real Housewives of Beverly Hills" star played 9-year-old Lindsey Wallace in the 1978 horror classic "Halloween." The film also starred a then-unknown Jamie Lee Curtis as iconic scream queen Laurie Strode, who is terrorized by a mysterious masked killer named Michael Myers.

We caught up with Kyle at the "RHOBH" premiere party on Wednesday night, where she talked to toofab's Lawrence Yee exclusively about her experiences on the "Halloween" set -- she even played cards with Michael during breaks from filming! Check out the video below to find out how the flick ended up "traumatizing" her for years:

This year marks the 35th anniversary of "Halloween," which was selected for preservation in the United States National Film Registry in 2006. It spawned seven sequels, a 2007 remake and that remake's sequel!
