Jack's acting idol is Heath Ledger. This stems from his love of A Knights Tale, which he first saw at the age of 11.
It only took Jack a month to be cast in his first official acting role.
Jack is no stranger to gaining muscle mass or slimming down for roles. He feels each of his characters deserve all of his time and effort to get them perfect.
Jack's entire right arm is covered in a large geometric style tattoo.
