Carrie Underwood’s “Two Black Cadillacs” song is becoming a TV show for Fox. Underwood is attached to executive produce the 6-hour “event series” with uber-producer Jerry Bruckheimer. The show from Warner Bros. Television will delve into a love triangle in the South. It gets murderous, naturally, when a wife and mistress catch on to a philandering man and plot to kill him. The song was written by Underwood, Hillary Lindsey and Josh Kear. It was on Underwood¹s 2012 album Blown Away and went platinum. Fox says that the show will be a “six-hour, limited event series.”
