3: The Devil's Backbone
This subtitled 2001 Gothic horror flick is one of Del Toro's best, but perhaps not the best place to start in his filmography. It's a chilling ghost story, a mysterious whodunnit, a revenge tale and, above all else, just plain scary. Set in an orphanage during the Spanish Civil War, a backdrop that will pop up again, the movie applies a fantastical layer over the horrors of war, painting a picture that will haunt you well after it's finished.
2: The Shape of Water
Two years ago this film, which, let us remind you, is about a woman who takes a fishman for a lover, won four Academy Awards, including the two biggies; Best Picture and Best Director. Consider how great a film with such an absurdly bizarre concept as inter-species lovin' has to be in order to just get nominated, let alone win. Kudos Del Toro, you wonderfully imaginative weirdo. Kudos.
1: Pan's Labyrinth
This haunting, grim fable is set in the fallout of the Spanish Civil War and has been described as "Alice in Wonderland for grown-ups". It's the movie where all Del Toro's cinematic strengths and fascinations - wild creativity, brilliant visual style, and deeper allegorical storytelling - were all truly realised. Full of startling, at times terrifying, images and telling a brutal and heartbreaking story, the film is a gloomy dark masterpiece to truly get lost in. If you only see one of the Mexican director's movies, make it this one.
