Following the unexpected successes, both critical and commercial (in its native China at least), of 2018’s Long Day’s Journey Into Night, Bi Gan returns with an even more spectacular and artistically ambitious epic, Resurrection, which also marks his first time in the Cannes Film Festival main competition. It’s no doubt the most challenging entry on the Croisette this year – the first 20 minutes or so are entirely devoid of spoken dialogue – yet brave souls who stick it out will eventually discover its internal logic and be richly rewarded.
