For Bonnie Wright, who has played Harry Potter's true love Ginny Weasley for 10 years, the rivalry is personal: Her off-screen love, Jamie Campbell Bower, costars in both franchises. In the Twilight saga he plays evil Volturi vampire Caius, and he'll portray powerful wizard Gellert Grindelwald in the upcoming Harry Potter and the Deathly Hallows.
But Wright, 19, says there's no question where her allegiances lie.
"Harry Potter all the way," she told PEOPLE at Wednesday night's grand opening of The Wizarding World of Harry Potter at Universal Orlando. "Since I was [9-years-old]."
In April, the U.K.'s Daily Mail reported that Wright and Bower, 21, had gotten engaged after a whirlwind romance.
How’s their love going? "It’s great," says Wright, who also said she was overwhelmed by the experience of walking into a fully realized Hogsmeade wizarding village at Universal Orlando. "I’m absolutely blown away," she said. "Shell-shocked."
