WE’RE more used to Twitter feuds between Z-list reality stars, however two of Hollywood’s biggest action stars could be embroiled in an online falling out.
Willis appeared in the first two instalments of the franchise as Mr Church, the CIA agent who gave the team their assignments.
The Rambo star tweeted: “WILLIS OUT... HARRISON FORD IN !!!! GREAT NEWS !!!!! Been waiting years for this!!!!”
Moments later he tweeted: “GREEDY AND LAZY ...... A SURE FORMULA FOR CAREER FAILURE.”
A representative for the actor confirmed that the tweet was aimed at Willis, but would not comment any further on the dispute.
The third Expendables movie is expected to enter production later this month, with an expected release in 2014.
58-year-old Willis has not yet commented on his decision to leave the movie franchise.
