Ludwig was born in Vancouver, British Columbia, Canada, to former actress Sharlene Martin and businessman and Lionsgate Entertainment co-chair Harald Horst Ludwig. He has three younger brothers and sisters. Ludwig was drawn to the industry because, as he stated in an interview, “I have a really active imagination. I enjoy performing.”

Ludwig had to persuade his parents to accept his wish to pursue acting as a youngster, despite his mother’s early career as an actor.

His parents were of the opinion that kid performers “may get lured into a world that isn’t realistic.” Ludwig studied drama at the University of Southern California, where he was a member of the Phi Kappa Psi fraternity.
