Shatner clearly has "it" and "it" clearly transcends character and time. He's the opposite of typecast. How many people have been the lead character in three successful TV shows? (Hint: Less than five actors)
Out of curiosity, how do you define "successful", and how do you define "lead", and who are your five?
Can a show be successful if it only ran one season? Ted Danson, for example, starred in Cheers, Ink, and Becker... does Ink's one season make it a successful series?
John Ritter starred in Three's Company (and the spin-off series), Hooperman, and Eight Simple Rules For Dating My Teenage Daughter... I've never heard of Hooperman personally, but it ran a couple of seasons...
Can someone be considered the lead character if they don't have top billing? Heather Locklear was a 'special guest' for six years seasons on Melrose Place, for example, and appeared in more episodes than anyone except Thomas Calabro. She was the female lead in Spin City for a couple of seasons - would that count? John Larroquette wasn't first billed on Night Court, but would it count? What about shows with two 'stars' - Moonlighting, Jeeves and Wooster, The Dukes of Hazzard - can either one count it as a tick?
Does voice work count? David Jason played Danger Mouse - unquestionably the lead character - in Danger Mouse. Does it count as one of his three?
Do 'The Dick Van Dyke Show' and 'The New Dick Van Dyke Show' count as separate series, given that apart from the name, the two were entirely separate sitcoms? How about 'Mission: Impossible' and 'The New Mission: Impossible', where the premise is the same, but only one character overlaps?
