Miller discusses 'Prison Break' future

Prison Break star Wentworth Miller has spoken about the show's next season, despite no official confirmation from the Fox network that it has been renewed.

Speaking to BBC Radio 1, Miller stated that the fourth season would address the ambiguity of his character Michael Scofield. "I think the question of how far across the line a good man can go before you can no longer call him good, is one that I'm looking forward to answering," he explained.

Miller is also keen for Prison Break to finish on a high, following the poor critical reactions and viewing figures for the third season. "I'm all for pulling the plug on our terms," he said, "before someone else does it for us."
