Russell Crowe warned Douglas Booth that working with him would be the most "interesting" thing he ever did.
The 23-year-old actor ran into trouble with his "Noah" co-star because he spent so much time on the set of the blockbuster texting his then-girlfriend, reported Femalefirst.
"I was on set in New York and always on my phone texting and I remember Russell coming up to me and saying, 'You're never going to be doing anything more interesting than working with me and (director) Darren Aronofsky. What are you doing on your phone?'
"And he was completely right. Now my phone doesn't come on to set so I stay present in every moment," Douglas said.
Douglas - who previously dated actress Vanessa Kirby and has also been linked with Taylor Swift, Emma Watson and Cara Delevingne - has just finished filming "Pride and Prejudice and Zombies" with Lily James, Matt Smith, Suki Waterhouse and Sam Riley.
