Shia LaBeouf used the wrong drug to prepare for his new movie Charlie Countryman, although its director has said that LaBeouf didn't need to take anything.
The actor dropped acid as research for the romantic thriller, but it has now emerged that the script has LaBeouf's character taking ecstasy.
Director Fredrik Bond told Vulture: "In the script, it's Carpathian ecstasy, a special hostel ecstasy that exists in maybe just Bucharest.
"So, Shia said he took acid? I didn't know he went out and said that. But it was always ecstasy in the script."
Bond went on to say that LaBeouf only told him he wanted to "go out on a limb and push the envelope", adding: "He said he wants to make this like they did in the '70s; he was like, 'I want it to be like there's a gun against my head'."
LaBeouf plays a young man who travels to Bucharest after his late mother appears in a vision.
During his journey, he falls in love with Gabi (Evan Rachel Wood) - who is married to a vicious and jealous gangster (Mads Mikkelsen) - and gets himself entangled in the Bucharest underworld.
Charlie Countryman is in UK cinemas now and open to limited theaters in the US on November 15.
