Dr. Who (Cushing films character) could conceivably mean the character from the real-world films.

I still think Dr. Who (fictional character) is the best option, because it's exceedingly unlikely that any reader would visit the page believing it to be for something else. (The Doctor's own article wouldn't be titled Dr. Who, and certainly not Dr. Who with disambiguation.)

As a sidenote, are we sure that the in-universe character's name includes the full stop?
