Comic book writer Joe Kelly is no stranger to having his works adapted for the screen. His 1997 run of Deadpool, arguably the definitive version of the character, played a major role in influencing the direction of the film.

R​LJE Films’ I Kill Giants is in theaters and on demand ​Friday, March 23.
