Jennifer Lopez's movie Unstoppable stopped on Friday due to the ongoing writers strike. Production on the wrestling drama flick — which stars the 53-year-old Maid In Manhattan actress — paused amid picketing by the Writers Guild of America, according to Deadline. It is unknown when the biopic — from her husband Ben Affleck's indie production company with Matt Damon, Artists Equity — will resume filming but is expected to pick back up at the end of the strike at the very latest, the publication reported.
