Toward the end, I'm watching the cop on the bridge warning Blake not to cross or he'll blow the bridge. He looks like Detective Quinn, the crooked cop on 'Dexter', so I look him up, and yup - it's him. He was also in last season's 'Justified'.
While I'm looking at the Batman credits on imdb.com, I also notice that Aiden Gillen was in it. He plays 'Littlefinger' on Game Of Thrones, but I can't find a scene he's in. He is credited as 'CIA Op'.
The most surprising was Senator Patrick Leahy of Vermont. He has now been in three: Batman & Robin, The Dark Knight, The Dark Knight Rises. He played Board Member #2 and is clearly seen when Miranda and Fox enter the board room, toward the end.
A lifelong Batman fan, Leahy has appeared in three films and one TV show about the Caped Crusader: he provided the voice for a territorial governor in the Old West on the animated series "Batman" (1992), made a cameo appearance as himself in the Jungle Party sequence from Batman & Robin (1997), and appeared in two of Christopher Nolan's Batman films, The Dark Knight (2008) (where he says to Heath Ledger's Joker, "We're not intimidated by you thugs.") and was "Board Member #2" in The Dark Knight Rises (2012). He also wrote an introduction for "The Dark Knight Archives," a 1992 compilation of Batman comics, and a preface for "Batman: Death of Innocents," a 1996 graphic novel about the dangers of land mines.
