Theirs is a bromance for the ages, and the Brits are bringing their talents Stateside for a limited run of No Man’s Land and Waiting for Godot on Broadway. Next up, the sirs return as their superhero alter egos – Stewart as Professor X, McKellen as Magneto – in X-Men: Days of Future Past.
But first, the two took some time out of their packed schedules Friday for an interview with BuzzFeed Brews, the site’s series of live-streamed Q&As. PEOPLE breaks down the best moments from their chat.
1. Hug it out.
When moderator Tommy Wesely asked if they ever tire of each other after working on so many joint projects, Stewart referenced their affectionate embrace before the show. “You’ve just seen us arm in arm over there on the side,” he said. “Does that look like two people who are sick of one another?” But McKellen won this round with a more direct reference to their loving friendship. “Ever since Patrick asked me to marry him in the summer,” he joked, “we couldn’t have been closer, could we?”
2. Bowled over on Twitter.
To publicize their plays, Stewart and McKellen Tweeted a series of seriously adorable pictures of them gallivanting around New York in bowler hats. The strategy certainly caught fans’ attention, and Stewart said he is amazed and grateful for the online support. “It has taken me by surprise, anyway, the response to the two of us doing silly photographs in exciting places and helping promote our show,” he said.
3. Blogging beginnings.
Speaking of the Internet, McKellen claimed that he basically created the blogosphere back in 2000 while shooting The Lord of the Rings in New Zealand. “I used to keep what I called an e-post, which was a regular diary – you know it as a blog. You’re looking at the guy who invented blogging!” he exclaimed. “Unfortunately I gave it another name and it didn’t catch on.”
4. The social network.
Just because they’re besties doesn’t mean these two don’t enjoy trading barbs. Explaining how social media has revolutionized show business, Stewart said, “It’s making us accessible to our audience, but – for us more importantly – our audience accessible to us.” McKellen interrupted, teasing, “How accessible have they been getting?” Laughing, Stewart shot back, “How much do you want to know?”
5. Speaking out about coming out.
The lighthearted talk took a touching turn when McKellen recounted what drew him to the role of Magneto in the first X-Men film. “Mutants are like gays, they’re cast out by society for no good reason and they, as in all civil rights movements, have to decide: Are they going to take the Xavier line, which is to somehow assimilate and stand up for yourself and be proud of what you are but get on with everybody, or are you going to take the alternative view, which is, if necessary, use violence to stand up for your own rights,” he explained. “And that’s true. I’ve come across that division within the gay rights movement.” McKellen, who is openly gay, also gave a shout-out to Ellen Page, who plays mutant Kitty Pryde in the movies. “That gladdened my heart so much,” he said of her coming out.
