(Cover) - EN Showbiz - Harrison Ford has allegedly called Shia LaBeouf a "f**king idiot" for criticising the movie they worked on together.

In a magazine interview, Harrison reportedly admits he found the young star too flippant when he spoke badly of their 2008 film Indiana Jones and the Kingdom of the Crystal Skull.

Shia previously said that he thought their movie did not do well because of legendary director Steven Spielberg "dropping the ball" with the plot for the movie.

Harrison did not find his words very professional and was upset that he trashed the movie so openly.

"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," he is quoted as telling Details.

"Shia is ambitious, attentive and talented and he's learning how to deal with a situation which is very unique and difficult."

Shia has also been vocal about working with Michael Bay on the set of the Transformers franchise and how difficult his former co-star Megan Fox found working with the director before she left the movie series. (C) Cover Media
