William Fichtner by Jordan Strauss/ WireImage.com
Prison Break's William Fichtner has broken out into a new role.

The actor, who plays Agent Mahone on the Fox series, has landed the lead role in the new TNT drama Night and Day, The Hollywood Reporter reports.

Joining him on the series is another TV familiar face: former ER staffer Sherry Stringfield.

Described as "fast-paced" and "gritty," Night will explore the life of Fichtner's Dan Hollister, a Bureau of Alcohol, Tobacco and Firearms agent who works for a special threat intervention task force. Stringfield will play his stay-at-home wife, Elizabeth.

It is unsure how the deal will affect Fichtner's role on Prison Break, but his contract expires after this season.

Night will be written and produced by Todd Robinson and 24 mastermind Joel Surnow, who helped Fichtner snag the role of Hollister. - Joyce Eng
