10 Best Performances In Prison Break

10. Don Self - Michael Rapaport

Sometimes the worst characters can be some of the most memorable, and in the case of Michael Rapaport's addition, as Homeland Security agent Don Self, he was already a questionable addition before the fourth season had even premiered.

If you were able to look past 'The War at Home' persona, you would have seen Rapaport play the role with an earnest sense of dedication - especially as a character who was way out of his depth and clearly making it up as he went along. That deserves acknowledgement at least.

Michael Rapaport earned equal degrees of frustration and sympathy from the audience - his character's sad backstory might have sprung out of nowhere, but if anything, it held up the motivations of the character, and made his back-stabbing motives more understandable.

The casting of Rapaport worked brilliantly - playing Self as a brash government bureaucrat who puffed up his chest whenever the brothers challenged him, only to reveal he'd been constantly spinning plates and was way over his head from jump.

His mid-season turn into a minor antagonist was a surprise, and from then on Rapaport did a tremendous job playing a contemptible a***hole as he tried (and sometimes successfully) one-upped even Michael.
