New set photos from The Flash reveal a mysterious figure stalking the grounds of Wayne Manor.Filming, which is currently taking place at the Burghley House in Lincolnshire, England, revealed a man in a long black coat walking the grounds. Twitter user @baines_stuart noticed that the figure was not wearing a robe over his costume, but rather that the coat -- and the long black beard the man was sporting -- is part of his costume. Whether this is a character in The Flash, a stunt person or a crew member remains a mystery.RELATED: Ezra Miller's Flash Gets a Comics-Accurate Makeover in This Electric Fan Art

Previous set photos from The Flash revealed that Wayne Manor will be a major location in the film -- specifically, the version of Wayne Manor from Tim Burton's Batman and Batman Returns. Michael Keaton will reprise his role as the Dark Knight, although he had previously cast doubt on his return to the role in March. Other cast members include Ben Affleck in his role as the DC Extended Universe's Batman and Sasha Calle portraying Supergirl.

The Flash is finally filming after cycling through multiple directors and screenwriters, after being first announced in 2014. The film will see Ezra Miller reprise his role as Barry Allen, with the Scarlet Speedster being pulled throughout the multiverse.

Directed by Andy Muschietti from a script by Christina Hodson, The Flash stars Ezra Miller, Michael Keaton, Ben Affleck, Sasha Calle, Kiersey Clemons, Ron Livingston, Maribel Verdú, Saroise-Monica Jackson and Rudy Mancuso. The film arrives in theaters Nov. 4, 2022.
