Che bel paesaggio: Bitter Campari (1984)

Fellini's segment on Spirits of the Dead

The Toby Dammit segment is also available in Criterion boxset but seems to be SD, so Arrow Blu-ray > Plaion Blu-ray > Criterion boxset Blu-ray

2014 Criterion Blu-ray is from the same master and has only slightly worse compression. JP/DE/FR releases all have incorrect levels. Caps

All Blu-ray releases are from the same mastering, superior to the one on older DVD releases which is sourced from a higher generation source. They all sound about the same, with the exception of Criterion, which sounds worse due to extraneous filtering.

Paramount's disc also includes a contemporary English dub, previously unreleased on home video.

Image Entertainment DVD is slightly better than Criterion 4K Blu-ray/Blu-ray/DVD (all basically the same)
Other Blu-ray releases are all much worse.
