Shia LaBeouf has revealed he is taking more "risks" with his career these days.

The actor - who found fame in blockbusters such as Transformers and Indiana Jones - appears in prohibition-era Lawless, which screened at the Cannes film festival.

He said he was gratified to have been a part of the film from start to finish, rather than, he said, "just piggybacking" on the success of a massive blockbuster. Shia, who also stars in Robert Redford's next film, The Company You Keep, hopes Lawless is the start of a new phase for him.

"I'm taking risks more," said the star.

"'I was really risk-adverse for a while because I had a big nugget to protect, not only for myself but for the people who were behind me. I think I've become less corporate."

Lawless director John Hillcoat said 25-year-old Shia "has been a prisoner of the franchise films for a while".

"He was so hungry for a real character, a real part," he said.
