Here’s a rumor from Clint over on MovieHole.net. They say Arnold Schwarzenegger is indeed returning for this new Expendables movie.
Schwarzenegger has arrived in Budapest to shoot his scenes in the Scott Waugh-directed spin-off, ahead of a Winter commitment to Ivan Reitman’s “Twins” sequel.Hungary currently requires visitors to quarantine for 10-days, which is why the “Predator” star has arrived ahead of the October shoot dates.
Although MovieHole has been right in recent times about new stuff for Laurence Fishburne and RoboCop, the problem with this is that the film will shoot in Bulgaria. However, Schwarzenegger has shot scenes in Hungary before, for a movie pretty much filming elsewhere (Terminator: Dark Fate).
What pretty much confirms this as not true however is the following Hungarian article, which says that rumors of him shooting a secret movie scene are not true and that he is just visiting a friend.
Although the Bulgarians started claiming Schwarzenegger was in the movie before any western rumors started, let’s not forget, finally, that Sylvester Stallone himself has denied any involvement from Arnold Schwarzenegger in this movie.
