Kevin McKidd, who plays Roman centurion Lucius Vorenus on the HBO drama Rome, will step into NBC's time-travel pilot Journeyman.
The NBC series follows a man who can travel back in time to "fix" people's lives. Sometimes, he inadvertently alters the future.
On Rome, McKidd's Vorenus is a moral soldier who falls from grace after the death of Caesar. The HBO/BBC series ends its run at the conclusion of the current season.
