Edoardo Ballerini appears in the seventh episode of Ripper Street as the character Frank Goodnight. Without (hopefully) being too spoilery, you can read some of his thoughts on filming Ripper Street. He also mentions that he auditioned for the part of the American Homer Jackson, which went to Adam Rothenberg.
You can find out more about Edoardo on his facebook page (which includes this photo from the set of Ripper Street)
