Actor Peter Sarsgaard has joined the cast of The Batman in a mystery role. Director Matt Reeves took to Twitter on Friday to announce his latest casting coup, prompting fans to speculate he might be the new District Attorney Harvey Dent, who becomes the villain Two-Face.
 
The character has previously been played on the big screen by Tommy Lee Jones and Aaron Eckhart.
 
Earlier, Sarsgaard's wife Maggie Gyllenhaal starred in Christopher Nolan's The Dark Knight as Assistant District Attorney Rachel Dawes, the romantic interest of Eckhart's Harvey Dent.
 
Reeves' new film, starring Robert Pattinson as Batman, will also feature Zoe Kravitz, Paul Dano, Colin Farrell, and Jeffrey Wright.
