This is more than likely false information but I said I would post it anyway out of interest.
According to imdb.com, Benjamin Ciaramello has been cast as The Riddler. There isn't even a 'rumoured' beside it.
Ciarmello has previously appeared as Santiago in "Friday Night Lights," as well as being featured in episodes of "Brothers and Sister"s and "Grey's Anantomy." He was briefly tipped to replace Taylor Lautner in "New Moon" when the latter hadn't been confirmed.
Does he have what it takes to play The Riddler, if this is not false information?
I don't know. I like Johnny Depp, but I've never seen him as The Riddler. David Tennant has been my personal favourite. I've never seen Ciaramello act but my favourite interpretation of E. Nigma has always been Brian Azzarello's in Joker, and maybe this guy could channel that?
Next on imdb: Dame Edna Everage to play Aunt Harriet? Gabriel Byrne to play Chief O' Hara? ;)
