The end of the trailer also shows us that Michael managed to get a note to Lincoln. Prison Break Season 5 will premiere next year in 2017.
Paul Kellerman is not featured in the trailer, but a report on Digital Spy states that he has signed up to return.
Alex Mahone, the troubled FBI agent portrayed by William Fichtner will not be returning. Robert Knepper who plays T-bag told Digital Spy the following about Mahone's fate.
"He didn't want to just bring everybody back, so that the audience go, 'Oh, look, it's Bill Fichtner again!' – he honestly thought, 'I'm not sure where to do that in the plot.'
"So if someday there's another chapter of this, maybe then Bill will be back. But I think the characters that are there, each of our moments that we have, are key to the storytelling, which is how it should be."
