WATCH: Keira Knightley Leads Awesome Cast in Trailer for Miss World Movie 'Misbehaviour'

The first trailer for Misbehaviour, the upcoming movie about the super-dramatic 1970 Miss World competition, has arrived – and it shows off the dramedy's stacked cast.

Keira Knightley stars as Sally Alexander, the activist who spearheaded a feminist protest against the contest as it unfolded at London's Royal Albert Hall in November 1970. Gugu Mbatha-Raw co-stars as Jennifer Hosten, that year's Miss Grenada, who beat the hot favorite, Miss Sweden, to become the beauty pageant's first ever black winner.

At the time, the Miss World contest was the most-watched TV event of the year globally, so the protest led by Alexander and fellow members of the Women's Liberation Movement became headline news.

The movie's supporting cast includes Keeley Hawes as the competition's organizer, Julia Morley, Greg Kinnear as its host Bob Hope, and Lesley Manville as his wife Dolores Hope. Look out, too, for Rhys Ifans, Wild Rose's Jessie Buckley, Downton Abbey's Phyllis Logan, and loads of early '70s fashion.

Directed by Philippa Lowthorpe (The Crown, Call the Midwife), Misbehaviour arrives in U.K. theaters on March 13, though its U.S. release details have yet to be confirmed. The trailer follows a first-look image of Mbatha-Raw in character as Jennifer Hosten, which appears below.
