Benedict Cumberbatch had a "difficult start" with his 'Doctor Strange' cloak.
The 40-year-old actor - who stars as the Marvel superhero in the hotly-anticipated movie - admits the garment was his favourite part of his costume, though he initially found it tricky to manoeuvre.
Asked his favourite part of the outfit, he quipped: "The cloak of levitation - we've got a good thing going and it has a large look out for me and I for it.
"We're beginning to work well together now, although it was a difficult start to the relationship - it going one way, me going another - it going on meal breaks when I needed to be in front of the camera and one or two contractual issues.
"But now we're very happy partners in crime."
Benedict undertook a huge amount of preparation for his role, from dieting and exercising to hone his physique, to watching videos of surgeons in action to get a feel for his character's regular job.
He explained in a webchat with The Guardian: "There were a lot of physical challenges to playing this role that involved the usual fitness regime and dietary discipline which I won't bore you with, but was certainly a help when it came to the obligatory shirtless moment.
"Beyond that need for a certain aesthetic, I really did need to get fit to keep healthy and also to do the kung fu fight sequences, car chases and aerial acrobatics in wires and on the gravity rig we use for what we term the Magical Mystery Tour moment where the Ancient One sends Strange on a trip through the multiverse.
"Intellectually, I read, talked to and watched (on YouTube) neurosurgeons at work - what a fascinating area of medical science, dealing in ethical as much as medical complexities.
"I read two fascinating, heartbreaking and inspiring books - Dr Marsh's 'Do No Harm' and 'When Breath Becomes Air' by Paul Kalanithi. Highly recommended reads whatever your interests, as both are beautiful and profound insights into human nature as much as their chosen professions and particular experiences."
