If you loved The Walking Dead, try Doctor X
A bridge between a film you've already seen and one most people haven't. Here's what they share, and what the second one does that the first one doesn't.
What they share

What Doctor X is
Foggy Manhattan nights, a lone typewriter clacking, a scientist's lab shrouded in shadows. A reporter crashes a mysterious investigation. Classic horror elements mark this Curtiz thriller.
