Oscar-nominated actor Benedict Cumberbatch has joined others in calling for the British government to pardon gay and bisexual men convicted in the past under the defunct "gross indecency" law.
Their letter published Saturday in the Guardian praised the government for the 2013 pardon of World War II code breaker Alan Turing, whom Cumberbatch portrays in the movie "The Imitation Game."
But Turing, a gay man in an era when homosexuality was illegal, was convicted of gross indecency in 1952 and committed suicide two years later.
These events are at the core of "The Imitation Game," which chronicles the role Turing played in cracking the Germans' "Enigma" code machine. It has been nominated for eight Academy Awards.
Turing was pardoned by Queen Elizabeth, but the letter pointed out that 49,000 other men convicted under the same law also merit pardons.
"The UK's homophobic laws made the lives of generations of gay and bisexual men intolerable," the letter said.
The letter was also signed by Rachel Barnes, Turing's niece; Morten Tyldum, director of "The Imitation Game," and actor Stephen Fry.
The letter calls on Prince William, his wife Kate and other "young leaders of today" to take steps to pardon all of the men, including an estimated 15,000 thought to still be alive. Thousands have signed an online petition calling for mass pardons.
