It is reported that Downton Abbey star Jessica Brown Findlay is one of five actresses testing for the love interest role in Captain America: The Winter Soldier.

Deadline.com, which broke the story, says that Brown Findlay, who plays Lady Sybil in Downton Abbey, is joined on the shortlist by Emilia Clarke (Game of Thrones), Teresa Palmer (Warm Bodies), Imogen Poots (Knight of Cups) and Alison Brie (The Five-Year Engagement).

The website also claims that Scarlett Johansson's Marvel character, the Black Widow, will "be in the mix" in the sequel to 2011's Captain America: The First Avenger.

The Joe and Anthony Russo-directed Captain America: The Winter Soldier, with Chris Evans in the lead role, is due in cinemas in April 2014.
