HBO’s Harry Potter reboot train has officially left the station and shows no sign of stopping. The upcoming series is slated for release on Christmas 2026, picking up the holiday trend where the Daniel Radcliffe-led franchise left off. Harry Potter has always been filled with whimsy – no matter what the desaturated and tonally dark reboot trailer may indicate. Harry Potter excels at the holidays, but that doesn’t mean the reboot will stick to all the decisions of the feature film franchise.
