Benedict Cumberbatch plays a neurosurgeon-turned-super hero in the upcoming Marvel blockbuster Doctor Strange. And from what we've seen of the footage so far, it's his most active role yet.
So how did he handle all those early morning wake-up calls from Hollywood personal trainers?
Well, the 40-year-old tells Be that preparing for all those sequences wasn't actually as tough as you'd think, even with a newborn in tow.
"It wasn't really taxing," he tells Be from the red carpet of the Hong Kong Doctor Strange fan event. "You have an awfully huge team to support you.

"So as long as you do your work, you're fine - you have a trainer to put you in a reasonably good physical condition to get you through the day and to look good if you need to do any shirts off stuff."
Oh, hello. Does this mean we're going to see Benedict get his shirt off as Doctor Strange? Brace yourselves, Cumberbabes.
He adds: "We had some incredible stunt coordinators. Some of which were from Hong Kong for the fight sequences and they really know what they're doing.
"The hardest part for them was reigning in an actor who's not done an awful lot of that all the time - bits here and there - but I'm not an action star per see, so just bringing myself up to speed.
"But it's the same for the character," Benedict explains. "He's good with his hands and he's a surgeon - he's not an action hero at the beginning of the film. So, in a way, his learning curve was also mine."
Earlier in the day, Benedict admitted that this action-based role was a step up from what he's used to.
"There were different demands for me doing a film of this scale,” the Sherlock star said of his first super hero role. “Whether it be the hours or the amount of live action involved.
"The physical side of things was a step up for me. But I think like a lot of actors, when you’re in a big film, you can’t think about that, you can’t think about what the preconceptions are going to be, you just try to problem solve moment by moment, day by day.”
“So [it’s] no different from any other role except more running around and physicality I suppose.”
So how did he get through those long shoot days and workouts then go home to a screaming baby?
Well, it turns out his now one-year-old son Christopher is a sleeper. Lucky Benny! Am I right, parents?
"Kit's a good sleeper and Sophie's a hero - a true hero," Benedict says. "I am very lucky. But, yeah, I had enough sleep."
In fact, his son Christopher, or Kit, as he so adorably nicknames him to Be, was also the real star of the Doctor Strange set.
“My baby was a great distraction,” Benedict said. “He was a soothing influence of the day…all these people running off four hours sleep and lots of caffeine suddenly [gaped in aww], he has that effect.”
Awww. Our hearts!
