USA Network's Burn Notice has brought on Patton Oswalt and The Wire's Sonja Sohn for guest-starring roles in the second half of Season 6.

Patton Oswalt will play Colin Schmidt, an unorthodox smuggler who is enlisted by Michael (Jeffrey Donovan) to escape the clutches of the CIA. It is also said that this quirky criminal's services come at a hefty price. The actor will appear in the 14th and 15th episodes of the season this winter.

Speaking of the CIA, Sonja Sohn will recur as a confident CIA director, who, "literally [wrote] the book on counter-intel training and procedures," according to insiders. The character will debut in Episode 13, although it isn't known how many episode she is slated to appear in.

Burn Notice airs its fifth episode of Season 6, "Split Decision" tonight, July 19, at 10 PM ET on the USA Network.
