Oh my God! The quarterback is toast!
~ Theo after a SWAT RV is blown up.

Theo is a supporting antagonist of the 1988 live action film Die Hard.

He was portrayed by Clarence Gilyard.


Theo is a weaselly, insensitive, and cocky terrorist who was the computer hacker for Hans Gruber and his crew in the course of their scheme to besiege the Nakatomi Plaza building.

Upon entering into the building, Theo assists Gruber's right-hand man Karl in killing the receptionist before going on to inform Gruber that the coast is clear; the crew then proceeds to take nearly over 30 attendees hostage. Theo is present in the boardroom when Gruber is interrogating Mr Takagi about the code to the vault. After Mr Takagi is shot point plank, Theo explains to Hans that of the 7 locks he can cut the first 6 but the 7th lock is an electro-magnetic seal that can't be cut locally.
