Thanks to TheDivergent.net for pointing this out! Actor Luke Kleintank recently tweeted the following:
This is still considered a rumor however, given that Luke Kleintank’s account is not verified and we have not gotten word from Summit about this testing. Kleintank is mostly known for his role in Bones (Finn Abernathy) and Haunted (Nick Di Santo). Also, he played Caleb Phipps in “Person of Interest” which is a slight coincidence to the character he is supposedly going for given the names. What do you think of him as Caleb? Keep your ear out for any more casting news, with production beginning in April names and roles will be trickling in very soon.
