I don't know why everyone keeps referring to 17 -- the Zac Efron movie in which a 40-year-old guy is suddenly a teen again -- as Big in reverse. Or, as The Hollywood Reporter writes today: "turns the concept of Big on its head." I guess nobody remembers the George Burns-becomes-Charlie Schlatter comedy 18 Again! Either that or it's simply easier to reference Big because it's a million times more well-known. Anyway, there's another movie 17 will make people think of: Back to the Future. Apparently, Efron's character (aka Matthew Perry's character as a teen) becomes the object of a crush -- from his own daughter! Playing the poor girl, who obviously doesn't realize her own Electra complex, is Michelle Trachtenberg. Also joining the cast, which includes Leslie Mann as Efron/Perry's wife and Trachtenberg's mom, is Melora Hardin ("Jan" on TV's The Office) as a high school principal.

So here's what I find strange about the new plot revelation: how is it the daughter doesn't recognize her own father as a young man? Hasn't everyone seen photos of their parents from when they were younger? At least with Back to the Future, in Lea Thompson's defense she hadn't yet birthed Michael J. Fox, and she had no way of ever having seen his face before he traveled back in time and became the object of her desires. In both scenarios, it is pretty gross to think about seriously. According to the main plot synopsis for 17, the reason Efron/Perry enrolls in high school is to be closer to his kids (hey, another movie this reminds me of: Mrs. Doubtfire). I guess he truly gets his wish in a terribly sick sort of way. Production on 17 begins this month.
