List of unproduced Dark Horse Comics projects

This is a list of unmade and unreleased projects based on Dark Horse Comics publications. Some of these productions were, or still are, in "development hell". Projects that have not provided significant production announcements within at least a year, would be considered in development limbo until further announcements are released. The following include films, television shows and video games, whether as live-action or animated productions.

Hellboy III
In July 2008, Guillermo del Toro expressed his interest in directing a third Hellboy film, saying that he would work on the film after finishing The Hobbit. In 2010, during the production of the unmade At the Mountain of Madness, del Toro mentioned that he would direct Hellboy III after his next project, even though the script was not yet written. del Toro later said in 2013 that the film was unlikely to be released, and suggested the possibility of telling its story in comic book form. Hellboy creator Mike Mignola refused to accept the idea.

In a Reddit AMA from July 2014, del Toro said:"Well, you know, we don't have that movie on the horizon, but the idea for it was to have Hellboy finally come to terms with the fact that his destiny, his inevitable destiny, is to become the beast of the Apocalypse, and having him and Liz face the sort of, that part of his nature, and he has to do it, in order to be able to ironically vanquish the foe that he has to face in the 3rd film. He has to become the beast of the Apocalypse to be able to defend humanity, but at the same time, he becomes a much darker being. It's a very interesting ending to the series, but I don't think it will happen. ... We have gone through basically every studio and asked for financing, and they are not interested. I think that the first movie made its budget back, and a little bit of profit, but then it was very very big on video and DVD. The story repeated itself with the second already, it made its money back at the box office, but a small margin of profit in the release of the theatrical print, but was very very big on DVD and video. Sadly now from a business point of view all the studios know is that you don't have that safety net of the DVD and video, so they view the project as dangerous'."

Although Ron Perlman revealed that he was working on a new Hellboy film, and del Toro was unlikely to return, del Toro later revealed that the third Hellboy movie was scrapped. A reboot was released in April 2019 with no involvement from Del Toro.

Hellboy: Silverlance
In 2010, Hellboy screenwriter Peter Briggs was asked by Universal to script a spin-off centering on Prince Nuada, and provisionally agreed that Briggs could direct the film in New Zealand. Briggs began work on an outline with co-writer Aaron Mason. Titled Hellboy: Silverlance, the script was a B.P.R.D. story featuring Abe Sapien as the main character with Hellboy in a supporting role. Moving into the new B.P.R.D. headquarters in Colorado, Abe is troubled by his psychic connection with Princess Nuala, and begins researching the elves' history. The film would have shown Nuada's adventures throughout history, including his rivalry with a fairy courtier who orchestrates Nuada's exile in hopes of marrying Nuala and seizing control of the fairy kingdom; Nuada first meeting Mister Wink by saving him from a troupe of soldiers during the Spanish Inquisition; and Nuada in Nazi Germany, engineering a pact to keep various supernatural entities safe during World War II (with Nuada and Kroenen fighting in a "friendly" match for Project Ragnarok men). Doug Jones would have played both Abe and the Angel of Death, who strikes a bargain with Nuada. Rupert Evans's Agent Myers would also have returned. The story climaxed at the new B.P.R.D. headquarters, with the return of Rasputin's summoning gauntlet. Universal wanted to proceed with the project, but it emerged that del Toro's Hellboy 3 was still a possibility, so Silverlance was shelved. In 2015, Briggs received another call from Universal, saying that Hellboy 3 had been cancelled and asking him and Mason to return for a reworked Silverlance, with producers del Toro and Lawrence Gordon involved. The caveat was that Hellboy could not appear, but the writers managed to get the character a cameo appearance at the climax. If successful, the film would have launched a From the Files of the B.P.R.D. spin-off series. In May 2017, Briggs affirmed that, with the announcement of the Hellboy reboot, the Silverlance project was dead.

Hellboy: The Phantom Claw film
A third animated Hellboy film, The Phantom Claw, was planned. Tad Stones, writer of Hellboy: Sword of Storms and Hellboy: Blood and Iron, said the film would have starred Lobster Johnson and have some familiar characters. The film was ultimately canceled.

The Mask II
Not long after the release of The Mask, an issue of Nintendo Power revealed that Jim Carrey would be returning in a sequel called The Mask II. The magazine held a contest where the first prize would be awarded a walk-on role in the film. Director Chuck Russell, who helmed the original film, expressed his interest in a Mask sequel in his 1996 Laserdisc commentary. He was hoping Carrey would come back as the title character, along with Amy Yasbeck, who played reporter Peggy Brandt in the original. In a 1995 Barbara Walters Special, Carrey revealed that he was offered $10 million to star in The Mask II, but turned it down, because his experiences on Ace Ventura: When Nature Calls convinced him that reprising a character he'd previously played offered him no challenges as an actor. Due to Carrey declining to reprise his role, the project never came to fruition, and the concept for the sequel was completely changed. The winner of the failed contest was given $5000 and other prizes, and was issued an apology in the final issue of Nintendo Power in 2012.

In 2001, Lance Khazei was asked by New Line Cinema to write a new script for a sequel to The Mask. Nothing came from this version of the sequel and the film was changed into the critically despised, box-office disaster Son of the Mask.

In August 2014, Mike Richardson said: "We've been talking about reviving The Mask, both in film and in comics. We've had a couple of false starts". There has been no further announcements.

Depp has expressed great interest in being a part of the Sin City franchise.

The Black Pearl film
Although The Black Pearl was originally co-written with his cousin, Eric Johnson, as a screenplay, Mark Hamill has reported difficulties getting Hollywood to make a film adaptation that matches his vision for the project. He first expressed a strong desire to direct a film version of the story in January 1996, months before the first issue hit newsstands. Hamill has allowed multiple production deals to elapse and announced several projected dates for the start of filming. At the L.A. Comedy Shorts Film Festival on April 17, 2010, Hamill said that he secured backing from British investors for a $7-million budget, and that he will direct the film. He made a formal announcement at the Cannes Film Festival in May. Hamill described his vision for the project as a "dark, edgy thriller" and that he was seeking an "R" rating for the completed film.
