In his autobiography, Luis Buñuel singled out the obscure Polish film, Rękopis znaleziony w Saragossie (The Saragossa Manuscript, 1965) as a personal favorite, one of the few pictures he saw more than once (three times, in fact). It was an adaptation of a novel by Polish author Jan Potocki, who left behind the incomplete work upon his suicide in 1815. Directed by Wojciech Has, the 182-minute epic surrealist film was severely edited (up to an hour) and fell out of circulation for decades. An uncut print eventually surfaced in 1999, thanks to Martin Scorsese and Francis Coppola, who were following the lead of Grateful Dead guitarist Jerry Garcia, the initial instigator and partial financier of its restoration. (The musician died in 1995, before he could see his favorite movie back in its original condition.) For assistance in solving some of The Saragossa Manuscript’s mysteries, go here.
