The BBC science fiction series Doctor Who qualifies as one of the longest running network serials of all time; it originally debuted in 1963 and lasted 26 years and 26 seasons, consistently reeling in massive cult following. Though the initial program wrapped in 1989, the BBC revived the central character and the series in 2005. Episodes still found the good doctor jetting around time and space in his TARDIS (a spacecraft masquerading as a British phone booth), but this time out, producers had given the episodes a distinctly modernized look, replete with hefty doses of CGI. Once again, the doctor revealed the ability to change bodies, justifying the producers' desire to change the lead actor from time to time.
