London - Studio bosses are desperate to secure the services of the Sherlock star whose uncanny facial resemblance makes him a dead ringer for Gary McKinnon.
Benedict Cumberbatch is being headhunted to play the controversial Pentagon hacker in a new biopic about the extradition evader's forays into US military secrets involving aliens.
Ab Fab star Joanna Lumley is likely to be offered the role of McKinnon's doolally mother Janis Sharp while comedian Rory Bremner has been pencilled in to play notorious First Earth Battalion commander and top Pentagon alien hunter General Albert Stubblebine III.
Cumberbatch, 35, has shot to TV fame and glory with his New Year portrayal of the legendary Sir Arthur Conan Doyle detective.
An impressive CV includes his 2002 role of Freddy in the Beeb's somewhat tedious hard core lezzie drama Tipping National Velvet.
Successive roles in the acclaimed Spooks series saw his popularity sore (sic) as a hot button TV actor and in 2004 he was nominated for a Bafta for his role as the nutty Brit physicist Stephen Hawking.
A spokesperson for the McKinnon campaign said today a movie about the alleged hacker's plight had to be a good thing if it spread the word about those dreadful Yanks.
Ab Fab co-star Jennifer Saunders is a near lookalike for ex-Spice Girl Geri Halliwell.
