Dakota Fanning (Jane)
Already a name pre-“Twilight” thanks to her spooky-good work as a child actress (in “I Am Sam” and “War of the Worlds” among others), Fanning is using the franchise to segue into the next phase of her career. She had the lead role in “The Runaways,” as self-destructive female rocker Cherie Currie, opposite Stewart.
Best-case scenario: She matures into a full-fledged star and versatile actress like Reese Witherspoon. (Fanning actually played the younger version of Witherspoon’s character in “Sweet Home Alabama.”)
Worst-case scenario: How much have you heard from Tatum O’Neal lately?
Odds for post-“Twilight” success: 5:1
