Jessica Kiang Nobody emerges unscathed — least of all the audience — from Vahid Jalilvand’s highly effective, deeply unpleasant “Beyond the Wall,” a morbidly violent allegory for the effects of state-sponsored trauma on the individual that places contemporary Iranian society somewhere on the map between the sixth and seventh circles of hell. A strange combination of intricate, almost sci-fi-inflected psychological thriller, splenetic social-breakdown broadside and two-hander (torture) chamber drama, it is an exercise in bravura filmmaking applied to a story so relentlessly grim you might wish it were a little less well-made, giving you an excuse to look away. In his 2017 film “No Date No Signature” (which won Best Director and Best Actor in Venice’s Horizons sidebar), Jalilvand pictured a stratified society teetering on the edge of legality and morality; here, however, it has toppled entirely into the abyss. The only way is down, and the filmmaker is bringing you with it.
