Dance 'didn't feel pressure on Postal'
The two-part show is an adaptation of the Terry Pratchett novel but Dance told TV Choice that he wasn't worried about pleasing the author's fans.
He explained: "It's very nice for Terry Pratchett and for us that there are so many fans of the piece, but you can't please all of the people all of the time.
"I believe Jeremy Irons played [my character] Lord Vetinari before, so there's probably a whole legion of fans who mourn the fact that Jeremy Irons isn't doing this one. I'm cheaper, probably."
Dance also revealed that he likes playing a variety of roles, adding: "The more against type the better. We're all victims of what we look like - you are what you are seen to be."
Going Postal begins on May 30 at 6pm on Sky1.
