I loved Page in “Juno.” She was smart, funny and refreshing. And if she seemed like the most together, mature 16-year-old in history, there’s a good reason: Page is 21 years old. But it isn’t that much of a stretch compared to Jonah Hill, who played a high school student in “Superbad” when he was 24… The all-time most extreme movie for this sort of thing was “Grease,” … Stockard Channing, who was a 34-year-old Rizzo. Thirty-four! The only less convincing teenager in recent memory was Greg Oden.
