Deadline was talking to Dominic Purcell and talked about Prison Break revival.

DEADLINE: What more can you say about the scene you were shooting at the time?
It was just basically me running into this prison to look for my brother, Michael (Wentworth Miller). I can’t reveal too much of the plot, obviously, but there was a reason why I was running in, and a reason why all the guards were running out of the prison. Because basically, the regime in Yemen had collapsed, it was in complete chaos and turmoil, and the gates were open so all the prisoners were released. And I’m running in trying to get through and find Michael, and I can’t. But then the iron bar hit me on the head, and apparently, the whole cage then collapsed on me after I hit the ground. But I didn’t feel that.

DEADLINE: What more can you reveal about storylines of the Prison Break reboot and your character?
PURCELL: It’s tying into what’s going on in the world today with terrorism. The show is taking place in Yemen; we’re dealing with ISIS and ISA, and obviously we left off with Michael presumably dead. He wasn’t, he ended up working for this organization. It got to the point where he couldn’t do it anymore, and they threw him in a jail in Yemen to change his mind. He didn’t change his mind, they set him up…Paul Scheuring has written all of the nine episodes. Honestly, the fans are going to be blown away by this. It’s really a riveting, high-tension thriller. It’s an extraordinary, extraordinary show. I’ve seen the dailies of it, and it looks like a cross between Bourne Identity and American Sniper. It’s crazy. It’s really, really cool.
