Hollywood supporting actor Michael Irby's mixed ethnicity enabled him to play characters from a broad array of cultural backgrounds -- from Obaid, one of the Middle Eastern men mistaken by Jodie Foster for a terrorist, in Robert Schwentke's ham-handed thriller Flightplan (2005), to Hispanic writer-in-training Reinaldo Povod (the brief recipient of Miguel Piñero's bisexual overtures) in the 2001 biopic Piñero. Irby's multiethnic quality also accounted for the malleability of his on-camera appearance (depending upon the dramatic situation); he was able to guest as multiple characters, for instance, on the series Law & Order. Irby culled the most widespread attention, however, for his series work on the prime-time military actioner The Unit, as special ops team member Charles Grey.
