Gotham:
Interview! Soaps.com sat in on a conference call with Robin Lord Taylor, who plays Oswald Cobblepot. Though the actor went into the audition blindly, in regards to how the process all came together Taylor shared, “It was amazing, and then when I read the script, it all just came together in such a brilliant way. The pilot script was one of the best ones that I’ve ever read. In terms of what I really responded to was the fact that this character, though, from all I’d ever seen, these larger than life, incredible performances of the character by Burgess Meredith and Danny DeVito, but what was brought to the page was just this humanity and the fact that we’re actually trying to bring some real human pathos to this fantastic character and this fantastic world. That was immediately what I just keyed into.”

In casting news… Nicholas D’Agosto (“Masters of Sex”) will turn up in a recurring role of a district attorney named Harvey Dent. If the series is a hit, D’Agosto could return for season two. Tune in Mondays at 8:00 PM on FOX.
