The Sleeper

In collaboration with the London Spanish Film Festival and Instituto Cervantes, the National Gallery is delighted to host the UK premiere of 'The Sleeper: El Caravaggio Perdido'.

Facing a move, the Pérez de Castro family puts up for sale at auction a painting that had been in their dining room for decades. The starting price, €1500. When antique dealers see the painting in the catalogue, they recognise it as a possible lost Caravaggio. An arduous and delicate process of restoration, attribution and sale follows. More than a documentary, 'The Sleeper' is a thriller which masterfully sheds light over the obscure intricacies of the antique art market, yet without letting it loose any of its fascinating mystery.

Following the screening the film's Director, Alvaro Longoria will be in conversation with Daniel Ralston, the National Gallery's CEEH Associate Curator of Spanish Paintings and Jorge Coll, CEO, Colnaghi.
