Variety's review assesses "The Echo Chamber," a single-location romantic drama directed by Andrea Pallaoro, based on the final screenplay co-written by Bernardo Bertolucci before his death in 2018. The film, starring Alicia Vikander and Luca Marinelli as new lovers whose relationship is complicated by addiction and recovery, is praised for its visual beauty and restrained direction but criticised for being overlong and narrowly focused, failing to expand beyond its central couple's fraught relationship.

The story unfolds in a luxurious London flat, with Vikander playing Anne, a doctor, and Marinelli playing Leonardo, a music producer with chronic back pain whom she treats and falls for. Susan Sarandon appears as Ava May, a singing icon Leonardo lures out of retirement to record an album. Told via a flashback-and-forward structure beginning at the relationship's crisis point, the film runs over two hours and is marked down for an "unnecessary" melodramatic twist late on, despite strong performances and cinematography by Diego Garcia.
