28 Years Later: The Bone Temple star Ralph Fiennes says Dr. Kelson is on a collision course with Jimmy Crystal "It's good and evil, isn't it?"

Ralph Fiennes as Dr. Kelson and Jack O'Connell as Jimmy Crystal in 28 Years Later: The Bone Temple.

Of the many surprises in 28 Years Later, few would have expected Ralph Fiennes' iodine-drenched, ossuary dweller Dr. Kelson to be the film's tender heart and soul. But Dr. Kelson's good man is set to meet his match in Jack O'Connell's psychopathic Jimmy Crystal when sequel The Bone Temple hits screens.

Picking up the story of Alfie Williams' Spike, who was rescued/captured (depending on how you look at it) by the Jimmys in spectacularly strange fashion at the climax of 28 Years..., The Bone Temple follows Spike's horrific time among the Jimmys, in parallel to Dr. Kelson's surprising experiments on Alpha-infected Samson (Chi Lewis-Parry). But as the two storylines converge, a battle of good and evil awaits.
