First thought I had about The Last House on the Left, upon seeing the cast, and then the trailer: wait a second, Monica Potter is old enough to play the mother of Sara Paxton? The math says yes... if you're stretching it. Potter is 37, and has 17 years on Paxton. Tony Goldwyn, her screen husband, is 11 years older. But the movie doesn't establish the couple as high school sweethearts, and in fact they have an even older, deceased son, the  brother of Paxton's character. So... I call bullshit. Good-looking bullshit, but bullshit nonetheless.
