With the news that Iraq has passed a bill making same-sex relations punishable by jail sentences of up to 15 years, it reminded me that jail sentences would have been applicable to me in the UK not so very long ago, and certainly in the Isle of Man where I grew up and entered adulthood.
The 1961 film Victim was very probably influential in leading to a change in British law in 1967. Same-sex relations were not decriminalised in the Isle of Man until 1992.
Matt Baume gives an excellent exposition on how courageous and influential the makers and actors of that film were.
