Two-Face to star too.
UK, March 9, 2010 - Batman's divisive sidekick Robin could be making an appearance in the forthcoming Arkham Asylum 2, with early cast listings revealing the presence of The Boy Wonder.
An IMDB listing for Rocksteady's sequel to its genre-defying Arkham Asylum confirms that Mark Hamill reprises his performance as The Joker, who's to be joined by Two-Face with actor Bruce Greenwood taking on the character.
What's likely to prove more controversial is the inclusion of Robin, to be played by Vincent Martella who most recently voiced Hope Estheim in Final Fantasy XIII.
Warner Bros. has been coy about the news, telling Kotaku "To our knowledge, what you asked about is inaccurate information. We are not yet discussing details for the sequel."
IGN's resident Batman expert Alex Simmons was keen on the potential inclusion, saying "I think it's a good idea. [Robin's] not as much of a dick as people think he is."
