The first photo of Meryl Streep as Margaret Thatcher was released by Pathé UK Tuesday.

Streep is currently filming The Iron Lady in London.

"The prospect of exploring the swathe cut through history by this remarkable woman is a daunting and exciting challenge," Streep, 61, said in a statement of becoming Thatcher, now 85.

"I am trying to approach the role with as much zeal, fervor and attention to detail as the real Lady Thatcher possesses - I can only hope my stamina will begin to approach her own," she added.

Streep famously became Julia Child in Julie and Julia and an Anna Wintour-inspired editor in The Devil Wears Prada.
