This has grabbed my attention. Three films I haven't seen, "Possession" being the one I have. Andrzej Zulawski: Three Films (Limited Edition Box Set) | Eureka
I've only seen Possession and That Most Important Thing: Love. Possession seemed a bit less than it should have been overall, but Adjani's performance is a must see. TMITL is currently streaming on Criterion, and it's pretty great. A performance by Romy Schneider to rival Adjani's, too.
A visionary director. Zulawski was skilled at drawing out intense performances from his actors. All three films in the set are well worth your time. It’s about time that his films receive the treatment they deserve.
