Known as the villainous T-bag from Prison Break, and with an appearance as the Clock King on Arrow, Robert Knepper's new role is as much a mystery for him as it is to fans of The Hunger Games franchise.

When asked by MTV what his role will be in the upcoming "Mockingjay" movie, Knepper admitted that he had no idea what he is in for, saying, "I don't even know yet! I know what I read for. I read, this was last summer... This is a huge movie. This is a huge two movies, and I know that what I got is not what I'll end up doing, they're so secretive about this."

EW's Popwatch noted that Knepper's character, Antonius, is nonexistent in the book series, and for a movie adaptation that is relatively loyal to its books, his character raises a lot of questions from frenzied fans.

There are some theories as to who this Antonius character is, and Popwatch shared some of theirs:

A soldier fighting for the Capitol - since Knepper is known for his bad guy roles, he may be a member of the Capitol army during the full-scale war against Katniss and the rest of the Districts.

A soldier fighting alongside Katniss in District 13 - he could also as easily be on the other side of war, fighting alongside Katniss instead of against her, but as Popwatch pointed out, people with Roman names (such as Antonius) usually hail from the Capitol.

A TV Crew member - the camera crew is almost always present, but putting a known face on a small role seems unlikely.

Peeta's Torturer - Peeta's plight has been nasty since he was tortured to the point of not knowing what was real and not, but with Peeta rescued early in the book, Antonius can't have that big of a role.

Fans will have to wait, though. According to Knepper, more of his role will be revealed in due time. "You're going to find out when I find out," he said. "Well, I'll find out a little bit sooner than you, but I still haven't found out for sure!"
