Dr. Who and the Daleks is the only canon entry in the entire Doctor Who mythos. To question otherwise would be foolhardy at best. It stars Peter "More Cushing For The Pushing" as Dr. Who and some Daleks as Daleks.
It's, like, the first ever Doctor Who movie. GET HYPE.
This was based off that Dalek episode everyone remembers
The Daleks (No Shit)
