The 22-year-old Divergent actress starred alongside Clooney in the 2011 film The Decendants -- the film that launched her to fame -- and according to her, the Oscar-winner has been a "blessing" in her life.
"He knew everyone's name on set," she said. "He treated everyone as an equal and everyone got his warmth."
Speaking of co-stars she's continued to be friends with, Woodley said that she hopes to be as close to Miles Teller -- her Spectacular Now and Divergent co-star -- as Clooney is to Julia Roberts.
"Their relationship I could see being our relationship in 20 years, and that really is special," she said.
The Fault In Our Stars actress also opened up about a few of the disappointments she's had since joining the entertainment industry, including the time she found out her role as Mary Jane Watson would be completely cut out from The Amazing Spider Man 2.
"For a few hours it was literally like, 'Oh, my God, was I awful? Why did they cut me? What are people going to think?'" she confessed. "I woke up the next morning and I was like, 'O.K., it makes total sense,' I'm a pretty spiritual person, so I can just sit back and trust that everything happens for a reason, even if my ego doesn't like it."
