Terminator Salvation director McG reflects on the poor response to the film and teases that a much darker cut exists. Released in 2009, the fourth film in the Terminator franchise serves as a soft reboot, introducing Christian Bale as John Connor in a post-apocalyptic story set after Judgment Day. Also starring Sam Worthington, Bryce Dallas Howard, and the late Anton Yelchin, the film was met with mostly negative reviews from critics and was considered something of a box office disappointment.
