Back in 2016, Synapse released a blu-ray of Tenebrae in deluxe and standard editions that was impressive. More recently, they've taken this Dario Argento favorite into the ultra high definition realm and created a version that offers impressive upgrades both in transfer quality and in terms of bonus features, collecting a bevy of material from multiple versions to create a monster of a set that will tantalize the director's fans.

…if you waited for an affordably-priced domestic UHD release for Phenomena, Synapse Films has amply rewarded you here. You get all three versions of the film in sterling presentations plus an impressive slate of extras that take you inside the complex story of this film's creation.
