Mr Spock, the half-human, half-Vulcan science officer aboard the USS Enterprise in the Star Trek TV series, has been declared a fraud by one fan of the show, who claims the 'half-alien' is none other than veteran actor Leonard Nimoy.
Mr Spock, whose real name is Spock, is portrayed as having semi-pointed ears, which the fan, 14-year-old Garth Zombolix, of Indianapolis, says are "not real", and "ludicrous", and would never appear on an alien, although Nimoy's real-life ears are 'a bit pointy'.
Zombolix, who was a member of the Trekkies until he grew up recently, claims that fans are being "duped", and wants Star Trek executives to own up to the lie, and to "apologise for the long and continued deception".
Star Trek was conceived by Gene Roddenberry in 1966, and has run ever since, captivating worldwide audiences with its realistic characters and plot lines. This latest allegation will come as a blow to the producers who are planning a further movie in 2009 entitled Star Trek: The Deception.
Other veteran actors under scrutiny from Zombolix are Deforest 'Bones' Kelly, who, he claims, is not really a doctor, and James Doohan, who played Chief Engineer 'Scotty' Scott. Doohan, he says, is not even Scottish, but Canadian.
Mr Nimoy said last night:
"This is completely illogical."
