Havas quickly put together a commercial featuring the Western Bacon Cheeseburger and the voice of actor Matthew McConaughey. Yes, the same voice that sells high-end Lincoln automobiles is now selling hamburgers. In the Carl's Jr. work he's only heard, not seen.
"That's the call of Carl's. Pick up," McConaughey says to end the spot.
His voice also plays a major role in the radio spots.
