Nightwatching is a 2007 film about the artist Rembrandt and the creation of his 1642 painting The Night Watch.

The film is directed by Peter Greenaway and stars Martin Freeman as Rembrandt, with Eva Birthistle as his wife Saskia van Uylenburg, Jodhi May as his lover Geertje Dircx, and Emily Holmes as his other lover Hendrickje Stoffels.

[2] An associated work by the same director is the documentary film Rembrandt's J'Accuse (2008), in which Greenaway addresses 34 "mysteries" associated with the painting, illustrated by scenes from the drama.

The film is centred on the creation of The Night Watch, Rembrandt's most famous work, depicting civilian militiamen who wanted to be celebrated in a group portrait.

The film posits a conspiracy to murder within the musketeer regiment of Frans Banninck Cocq and Willem van Ruytenburch, and suggests that Rembrandt may have immortalized a conspiracy theory using subtle allegory in his group portrait of the regiment, subverting what was to have been a highly prestigious commission for both painter and subject.
