Guillermo Del Toro's lasting influence on horror films extends far beyond writing and directing feature films. Del Toro is also an accomplished producer, putting his money and influence toward both his own titles and the titles of other genre filmmakers.

While movie producers may not get the same credit as directors, they play an equally important role in how a film turns out. Producers work behind the scenes to coordinate all the logistics, arrange the financing, and secure distribution. They also pick directors, as well as other key crew members Their input can either enhance or undercut a director's vision.

The Witches (2020) - 5.3

Del Toro is one of five producers who worked on Robert Zemeckis's The Witches, a dark fantasy comedy based on the Roald Dahl book of the same name. The second adaptation of the novel after Nicolas Roeg's 1990 movie, The Witches stars Anne Hathaway, Octavia Spencer, and Stanley Tucci.

Set in 1967, the film follows a young boy who encounters a large gathering of witches while vacationing at a seaside resort. While it features strong lead performances and impressive special effects, this iteration of The Witches lacks the superior writing and perfectly-pitched tone found in Roeg's well-received adaptation.

Don't Be Afraid Of The Dark (2010) - 5.6

In addition to producing Don't Be Afraid of the Dark, del Toro also co-wrote its script alongside Matthew Robbins. Based on a made-for-TV film from 1973, the big-screen remake stars Katie Holmes and Guy Pearce as a couple who move into a Victorian Rhode Island mansion with their dejected daughter Sally.

Sally, played by Bailee Madison, catches onto the fact all kinds of supernatural monsters are emerging from the ash pit in the house's basement. Don't Be Afraid of the Dark challenges atmospheric horror, but its plot falls apart as the dangers in the house grow more prominent.

Splice (2009) - 5.7

Del Toro was part of the large production team behind André Øvredal's adaptation of the popular Scary Stories to Tell in the Dark series of children's books.

Del Toro did it all on Crimson Peak: produced, directed, and co-wrote the screenplay. This throwback to Gothic horror features a gorgeous, creaking English estate occupied by characters brought to life by Mia Wasikowska, Tom Hiddleston, Jessica Chastain, and Charlie Hunnam.

Wasikowska plays American heiress Edith Cushing, an aspiring writer who becomes romantically involved with Hiddleston's Sir Thomas Sharpe.

The Devil's Backbone (2001) - 7.4

The floating ghost of Santi in The Devil's Backbone

Del Toro's third feature film, The Devil's Backbone solidified his status as a horror director to watch on the international stage. In addition to directing and co-writing this Spanish-language heartwrenching horror film set during the Spanish Civil War, del Toro also served as executive producer.

In 1939, a young boy named Carlos arrives at a remote orphanage after his father is killed.

Another Spanish-language film produced by del Toro, The Orphanage combines familial drama with supernatural horror. In it, a woman named Laura returns to her childhood home, an orphanage, intend upon reopening it as a center for children who have disabilities.

With her husband Carlos and adopted son Simon, Laura works on making her dream a reality. Young Simon soon discovers another presence in the old orphanage, and the film launches into one creepy, climatic scare after another.

Even though its events transpire during the Spanish Civil War, Pan's Labyrinth deals with timeless themes like the brutality of war and the enduring importance of myth-making. Yet another example of del Toro's triple threat of directing, writing, and producing, Pan's Labyrinth is a masterful dark fantasy tale.

Part creature feature, part historical melodrama, part coming-of-age story, this stunning film sets its sights on 10-year-old Ofelia. Ofelia escapes her tyrannical stepfather by exploring the old labyrinth near her new home, where she comes face-to-face with her destiny.
