MoC and BFI differing restorations and scores

2006 Restoration: Eureka Blu-ray
1995 photochemical restoration: BFI Blu-ray that some may prefer

Eureka with Murnau institute restoration featuring score based on original score, BFI uses Photoplay restoration with James Bernard score

Both Eureka and BFI BDs are worthy of owning. Each restoration has unique positives and extras. The James Bernard score on the BFI is outstanding and the image tinting is different to how the Murnau institute official restoration was done. The Eureka MOC BD is stuffed with extras and remains one of the best made BDs of all time. Whatever you do: AVOID THE KINO BD!!! It uses the same Murnau institute restoration but drops frames for the whole feature-thus it loses a significant portion of the film! This was never acknowledged or addressed. The Kino BD remains one of the worst BDs of all time for this reason.

Criterion Blu-ray

Criterion Blu-ray is slightly superior to BFI but Criterion is 1080i and BFI is 1080p see caps 

Criterion also only has English intertitles while BFI has both

2012 BFI Blu-ray

The 2025 BFI Blu-ray isn't a new remaster, and itonly has a Pet Shop Boys score. it's somehow more cropped than the 2012 BFI Blu-ray.
