The Thing on a train… so think Agatha Christie’s
The Thing From Another World Murders on the Orient Express and you have a pretty good idea about what it all entails. Lee and Cushing play
men of science who accidentally let an ancient monstrosity run amok on the locomotive, which would already be bad enough… but there’s more. Turns out, this damn dirty ape kills by sucking the intelligence out of its victims. On top of that, it can mind-swap with people, taking over the bodies of whoever looks into its eyes (that’s where Campbell’s influence comes in). At least the passengers can take solace in the fact the trip won’t be boring!
