Charlie Brown
From Tardis Wiki, the free Doctor Who reference
During Donna Noble's brief transformation into a half-Time Lord, as her mind began to overload, she confused Charlie Chaplin with Charlie Brown immediately after suggesting that she and the Tenth Doctor go meet Chaplin.
She immediately corrected herself, noting that this was not a feasible idea because Charlie Brown "was fiction". (TV: Journey's End)
Behind the scenes
- Charlie Brown, the main protagonist of the Peanuts comic strips — who is always referred to by his full name, and never simply as "Charlie" — was referenced in the comic story The Glorious Dead where one of the Doctor's counterparts from parallel universes, Theta Stigma, resembles Charlie Brown, while the Rani resembled Lucy van Pelt.
