Harrison Ford has revealed that he called co-star Shia LaBeouf a 'f***ing idiot' for criticising Indiana Jones and the Kingdom of the Crystal Skull.
LaBeouf joined the hit franchise back in 2008 when it returned to the big screen but openly criticised the film after it's release.
And this was a move that veteran star Ford did not agree with.
Speaking to Detail magazine the actor said: "I think I told him he was a f**king idiot.
"As an actor, I think it's my obligation to support the film without making a complete ass of myself.
"Shia is ambitious, attentive, and talented - and he's learning how to deal with a situation which is very unique and difficult."
Indiana Jones and the Kingdom of the Crystal Skull went on to be the biggest grossing movie in the franchise as it grossed $786 million worldwide.
A fifth movie is rumoured to be in the pipeline.
Ford will be back on the big screen this summer as he teams up with Daniel Crig for Jon Favreau's Cowboys and Aliens.
