Sylvester Stallone announced the news on Tuesday (Aug. 6) via Twitter: "WILLIS OUT... HARRISON FORD IN !!!! GREAT NEWS !!!!! Been waiting years for this!!!!" (Creative punctuation and spacing all a product of Stallone's, natch.)
He followed his announcement up with a jab at Willis, tweeting, "GREEDY AND LAZY ...... A SURE FORMULA FOR CAREER FAILURE."
Lionsgate has the Nu Image/Millennium Films action-adventure threequel set to open Aug. 15, 2014. Stallone returns as Barney Ross, the leader of a group of mercenaries that undertakes seemingly impossible missions. This time around, Jackie Chan and Nicolas Cage are due to take part in the fun, as well.
