“Pressure,” Tom Hiddleston says, “is a privilege.” He apologises for
appropriating the title of Billie-Jean King’s memoir, but it’s a sentiment that feels
pertinent to him and his co-star Hayley Atwell. They have known each other for 20
years, have both starred in the Marvel universe (Hiddleston as the charmingly
villainous Loki; Atwell as the wartime spy Peggy Carter), but this is the first time
they have worked together — if you don’t count their group audition to get into
drama school.
