The Taken franchise has spanned six years and three films. And during that period Liam Neeson, who plays former government operative Brian Mills, has been “the best fake movie dad any girl could ask for” to his fictional daughter Maggie Grace. During an appearance on Conan, Grace told the story of how Liam Neeson prank-called an ex-boyfriend who broke her heart. To exact revenge, Neeson put on his best set of skills — as Brian Mills — and warned the boy never to cross her again. Pro tip: Don’t break Maggie Grace’s heart or Liam Neeson will break your arm.
