After making three "Taken" films and several other "Taken"-like movies,
Grace was on "Conan" on Thursday to promote "Taken 3" and revealed that Neeson once unleashed his brand of cool menace on an ex-boyfriend that had once treated Grace with a lack of proper respect.
"I was a little bit heartbroken and he was kind of a hot mess," Grace said. "I was telling Liam about it because he always asks about my love life, or lack thereof. And he was like 'This just can't be. We have to set this kid straight.' "
Enter the menacing phone call. Neeson called the ex-boyfriend at his office and took on the persona of his "Taken" character, former CIA operative Bryan Mills.
"We've never met, and if you play your cards right, we never will," he said on the phone. (Luckily, Grace recorded the whole thing for posterity.)
He then threatened to break the ex-boyfriend's arm if he ever made another mistake again.
Actors have a history of using their tough personas to help out friends.
And Neeson himself helpfully threatened a fan in the audience during a recent appearance on "Jimmy Kimmel Live."
Neeson may play a tough guy, but he obviously has a heart of gold.
