“Reminiscence,” a film starring Hugh Jackman and directed by “Westworld” co-creator Lisa Joy, has been bumped from the Warner Bros. release slate, while the “Mortal Kombat” reboot has slid back by three months to fill that slot.“Mortal Kombat” will now open April 16, 2021 in IMAX, the same day that “Reminiscence” was meant to open.
