Tom Holland Brings 'The Lost City Of Z' to London

Tom Holland knows how to wear a suit well!

The 20-year-old British actor stepped out for the premiere of his new film The Lost City Of Z alongside co-stars Charlie Hunnam, Robert Pattinson (with fiance FKA twigs), and Sienna Miller at the British Museum on Thursday (February 16) in England.

Mr. Robot star Rami Malek was also there.

The movie follows British explorer Percy Fawcett (Hunnam), who journeys into the Amazon at the dawn of the 20th century and discovers evidence of a previously unknown, advanced civilization that may have once inhabited the region.

Despite being ridiculed by the scientific establishment who regard indigenous populations as “savages,” the determined Fawcett � supported by his devoted wife (Miller), son (Holland) and aide-de-camp (Pattinson) � returns time and again to his beloved jungle in an attempt to prove his case, culminating in his mysterious disappearance in 1925.

The Lost City Of Z hits theaters nationwide on April 21.
