Ian McKellen and Helen Mirren are teaming up for The Good Liar, a thriller from New Line directed by Bill Condon. Mr. Holmes writer Jeffrey Hatcher penned the script based on a novel by Nicholas Searle. New Line acquired the rights to Searle’s book in 2015 after a bidding war. Searle is actually the pen-name of an anonymous author who used to work as a civil servant in the UK.
