Fan CastingThe Beast from 20,000 Fanthoms (2013)

A nuclear bomb is set off in the Arctic as a test. Tom Nesbitt and George Ritchie go on patrol near the area of the blast. Suddenly, a giant prehistoric monster creates an avalanche, injuring Nesbitt and killing Ritchie. After waking up in a New York hospital, Nesbitt tells his story, only to be dismissed as crazy. After searching around for someone who believes him, Nesbitt ends up meeting paleontologist Thurgood Elson and his assistant, Lee Hunter. Elson doesn't believe Nesbitt, but Hunter isn't so quick to dismiss him. She visits Nesbitt with drawings of every known dinosaur. After a lot of flipping through pictures, Nesbitt recognizes the one he saw, the Rhedosaurus. After a lot of trouble, he meets a survivor of a shipwreck who claims to have been attacked by a monster. When handed several of the dinosaur pictures, the survivor identifies the Rhedosaurus as the creature he saw. With this proof, Nesbitt goes back to Professor Elson, who is convinced and warns Colonel Jack Evans of the danger. As disaster after disaster occurs, Elson connects the dots and determines that the Rhedosaurus is coming to New York. Being very enthusiastic on the subject, Elson has a scientific expedition set up to find the monster. He also insists on going down in a bathysphere to see the Rhedosaurus up close. He gets his wish; the Rhedosaurus attacks the bathysphere offscreen, killing Elson. It doesn't take long before the beast finally reaches New York and goes on a rampage.
