If it's been a while since you watched the 1978 Halloween, you may have been a little confused by someone in tonight's trailer for Halloween Kills that appeared to be Real Housewives star Kyle Richards. But, yes, that was her. Richards appears in the new film, reprising her role of Lindsey Wallace from the original film. Lindsey was one of the kids being babysat by Annie Brackett in the film, and would appear again in Halloween II (since it takes place on the same night as Halloween) and Halloween 4: The Return of Michael Myers. In the latter, she was a teenager, played by Leslie L. Rohland.
