His close friends call him ‘Serena’. Meant as a campy play on ‘Sir Ian’, it’s an oddly appropriate nickname for an actor who exudes an air of such immaculate serenity. Whether he’s glad-handing X-Men fans on the red carpet, defending gay rights in his role as co-founder of Stonewall or saving Middle Earth as Gandalf the Grey, Ian McKellen is the calm eye of whatever storm happens to be raging.
And he’s just as laid-back in person, spending a fair portion of our interview umm-ing, aah-ing and gazing wistfully out of the window – not in a senior-moment sort of way, but with the confident demeanour of a man who simply refuses to be hurried. But like any stage veteran, he does occasionally show his thespian streak: grabbing his back theatrically to evoke the aches of old age, or grinning slyly as he recounts a cheeky anecdote about working with Will Smith.
We’re discussing Mr Holmes, in which the 75-year-old dons ageing make-up to play a 90-year-old Sherlock Holmes, who’s living in a quiet corner of post-WWII Sussex until an old case rears its head. It’s an incredibly controlled performance, packed with pathos and subtlety: not as crowd-pleasing, perhaps, as Gandalf or Magneto, but every bit as memorable.
