Erica Durance (“Smallville”), Daniel Gillies (“The Vampire Diaries”) and Kristopher Turner (“Rookie Blue") co-star.

Finally, “American Ninja Warrior” premieres on G4 at 9 p.m. ET on Sunday, May 20. On the show, inspired by the original Japanese program, athletes from allover the country will compete in a tricky obstacle course in order to find the true “American Ninja Warrior.” G4 and NBC collaborated with the original Japanese broadcaster, Tokyo Broadcasting System Television.
