Call The Midwife's Jenny Agutter has said she couldn't think of "anything better than stepping out" of her usual role to beat up Robert Redford in Captain America: The Winter Soldier.
The 70-year-old actress played a member of the World Security Council, which oversees S.H.I.E.L.D in the 2014 sequel to Captain America: The First Avenger.
Agutter is seen attacking the Hollywood actor, 86, during a scene in the film, until she is revealed to be Black Widow, played by Scarlett Johansson, in a virtual disguise.
