There are a confusing number of different surviving prints, restorations and alternate versions of Nosferatu. In the main, there are three 'complete' restorations and two incomplete, partially-restored versions. All five are available on DVD, while the latest two restorations, from 1995 and 2006, are also on Blu-ray. In addition there are countless low-quality public domain DVDs with different lengths, running speeds and soundtracks. All are derived from a single print held by the Museum of Modern Art (MoMA). They usually have replacement American intertitles and are always in black and white; the film was originally color tinted throughout and only meant to be seen that way. This comprehensive article explains all of them simply and clearly: Nosferatu: The Ultimate Blu-ray and DVD Guide.
