The British actress, 26, played an undead – albeit drop-dead gorgeous – Jane Bennet in Pride and Prejudice and Zombies: Dawn of the Dreadfuls, a prequel to the Jane Austen parody Pride and Prejudice and Zombies.
So who is this budding actress making the leap from zombie vixen to Royal Highness?
This regal role will be Luddington's first time in the shoes of a leading lady. Her previous credits include small stints on CSI: Crime Scene Investigation and Days of Our Lives, as well as the part of "Uppity Guess #2" in a 2009 made-for-TV movie, Serving Time.
Obscurity aside, Luddington does have something in common with the princess-to-be: She hails from the British county of Berkshire, the same place Middleton, 29, grew up.
And she's not all beauty – like Middleton, she's brains, too. Luddington is Oxford University-educated, according to U.K.'s Sun, while Middleton attended the University of St. Andrews – the place where she first met Prince William as a 19-year-old college freshman.
As for researching for the role for the film, which is reportedly in high-gear in order to premiere in time for the April 29 wedding, Luddington's good-to-go, according to her sister.
"Camilla is very excited," she said. "She has always followed the Royal Family and never dreamt she'd be playing in a movie about them."
Luddington's prince will be played by Nico Evers-Swindell, a fellow newcomer.
