Sienna Miller stunned in Alexander McQueen, hitting the red carpet at the London premiere of The Lost City of Z, held at the British Museum on February 16, 2017 in London, United Kingdom.
The blonde beauty was joined on the red carpet by costars Charlie Hunnam and Robert Pattinson, who brought longtime partner FKA Twigs as his date for the evening.
Directed by James Gray, The Lost City of Z is set at the start of the 20th century, with British explorer Percy Fawcett (Charlie Hunnam) traveling into the Amazon. There he finds evidence of a previously undiscovered, advanced civilization that may have inhabited the area. A laughing stock in scientific circles, as indigenous people are viewed as savages, Fawcett takes his family back to the jungle, determined to prove his case.
‘THE LOST CITY OF Z’ HITS THEATERS ON APRIL 14, 2017.
