Prepare for The Day of the Doctor, as the "Doctor Who" 50th anniversary approaches. 

My family has been watching reruns of this BBC sci-fi series since the early 80s, from doctors Jon Pertwee and Tom Baker through David Tennant and Matt Smith (pictured). Now John Hurt is added to the equation. 

It's two weeks away, fans. 

See the trailer below.
