While speaking at the Oxford Union, McKellen said, "People must be called out and it's sometimes very difficult for victims to do that. I hope we're going through a period that will help to eradicate it altogether. But from my own experience, when I was starting acting in the early sixties, the director of the theatre I was working at showed me some photographs he got from women who were wanting jobs, some of them had at the bottom of their photograph 'DRR' - directors' rights respected."
The 'Mr Holmes' star added, "In other words, if you give me a job, you can have sex with me."
The 'Vicious' star hopes it will be "eradicated altogether", but in reality, he is less hopeful that this would be the case.
Sir Ian McKellen, who workd with Kevin Spacey in 2004, when Spacey was artistic director at the 'Old Vic in London' said that the timing of Spacey's own coming out was not ideal.
"The circumstances in which he chose to do it are reprehensible because it linked alleged underage sex with a declaration of sexuality," explained the 'Da Vinci Code' star.
