The following is a list of unproduced Robert Rodriguez projects in roughly chronological order. During his long career, film director Robert Rodriguez has worked on a number of projects which never progressed beyond the pre-production stage under his direction. Some of these projects are officially cancelled or fell apart in development.
1990s.
"Madman" film.
In 1998, Rodriguez acquired the film rights to Mike Allred's "Madman" comics. Both he and Allred gave numerous signals as to the start of production over the years, but as both had been occupied with other projects (Allred was instrumental in connecting Rodriguez with Frank Miller, leading to the production of "Sin City"), no results emerged despite both remaining eager to see the film made. In a 2000 interview, Allred mentioned that he had had contact with Robin Williams for the role of Dr. Flem. At a February 2006 appearance at WonderCon, Allred announced that he and Rodriguez hoped to begin filming in May of that year, he teased fans in attendance by saying that the titular role had already been cast, "but I can't tell you who it is yet." However, in December 2006, it was announced that George Huang would take over writing/directing duties, with Rodriguez stepping back to a producer role, in a January 2007 interview, Allred indicated that no roles had been cast yet.
In 2015, Allred indicated on Twitter that the rights to "Madman" had reverted to him, and in June 2018, stated that a film production "would have to take a set up even better than what I had with [Robert Rodriguez]" which he considered unlikely.
"Predators".
In 1994, Rodriguez wrote an early script for a third "Predator" film for 20th Century Fox while he was working on "Desperado" at the time. Rodriguez presented the script to the studio, but was denied when they realized that the budget would be too large. Fifteen years later, the studio decided to go with his script. Rodriguez stated:
It's the story from that script I had written way back then. They had hired me to write a "Predator" story while I was waiting to do "Desperado" back in 1995. It was crazy, this thing I came up with. So then fast-forward to now and, like, six months ago, they found the script and called me up. 'Hey, we want to redo this franchise and we found your old script. This is where we should have gone with the series! We want to move forward.' And that's what we're doing.
In 2009, 20th Century Fox studio executive, Alex Young, called Rodriguez to consider using his treatment to revive the individual Predator franchise. "Predators" was produced at Rodriguez's Troublemaker Studios as opposed to 20th Century Fox so that Rodriguez had more creative control over the film. It was originally thought that Rodriguez would direct, but on July 1, 2009, Nimród Antal was officially signed on to direct.
"The Mask of Zorro".
In 1995, Rodriguez signed on to direct "The Mask of Zorro" with Antonio Banderas for TriStar Pictures and Amblin Entertainment.

Rodriguez wanted a budget of $45 million and the studio only wanted to do a $35 million film. The film was eventually released in 1998, directed by Martin Campbell, who reteamed with Banderas in 2005's "The Legend of Zorro".
"Kiss Me Deadly" remake.
On the director's commentary track for "Sin City", Robert Rodriguez said that he had been attached, in 1997 or 1998, to direct a remake of the 1955 film noir, "Kiss Me Deadly".

2000s.

In 2001, Rodriguez thought about exploring other avenues for the "Spy Kids" franchise after '. Rodriguez is quoted as saying "TV, animation, specials, books, rides and toys. We're keeping the brand of "Spy Kids" alive." In 2002, he then said it may continue as a cartoon series after '. In 2005, Rodriguez also thought about making a fourth "Spy Kids" movie, which would have been animated and direct-to-DVD. Neither the movie or the cartoon ever materialized.

Filming was set to begin in 2005, with Rodriguez planning to use the all-digital stages he was using for his production of "Sin City", a film based on the graphic novel series by Frank Miller. Rodriguez planned to hire Frank Frazetta, the popular Burroughs and fantasy illustrator, as a designer on the film. Rodriguez had previously stirred-up film industry controversy owing to his decision to credit "Sin City"'s artist/creator Miller as co-director on the film adaptation, as a result, Rodriguez decided to resign from the Directors Guild of America. In 2004, unable to employ a non-DGA filmmaker, Paramount assigned Kerry Conran to direct and Ehren Kruger to rewrite the John Carter script. The rights to the film would be acquired by The Walt Disney Company, and would be eventually see release in 2012, directed by Andrew Stanton and written by Stanton, Mark Andrews, and Michael Chabon.

It has also been reported by Rotten Tomatoes that Edgar Wright may expand "Don't" into a feature film. According to Eli Roth, he and Edgar Wright have discussed the possibility of pairing "Don't" with "Thanksgiving" for a "Grindhouse" sequel. Roth is quoted as saying "We're talking to Dimension about it. I think they're still trying to figure out "Grindhouse 1" before we think about "Grindhouse 2", but I've already been working on the outline for it and I would do it in a heartbeat."
Electra and Elise Avellan, Rodriguez's nieces who play the Crazy Babysitter Twins in both films, originally stated their uncle wanted to do a sequel featuring both "Machete" and "The Babysitter Twins", but the latter concept did not materialize with the former's release. In an interview, Electra Avellan discussed a sequel with "Robert mentioned something about the end of the world and Hollywood action films, where we'd be trained in Mexico to come back here and fight."

2010s.

 ;templatestyles src="Template:Blockquote/styles.css" / ;
In 2010, Rodriguez confirmed that there would eventually be a "Predators" sequel:
 ;templatestyles src="Template:Blockquote/styles.css" / ;"[The studio] said, 'Let's do some other ones. What other story ideas do you have?'" says the filmmaker. "Because it was like, let's test out the market with this one. They really wanted it to be pretty contained, pretty scaled-back. They didn't want to put too many of the ideas into it that we could save for a second one. So we could see what the appetite was, because the bigger movie would actually be what comes following that. That kind of sets up a new storyline, new location and world, and then you can really go crazy from there."
Adrien Brody also spoke about reprising his role in a possible sequel:
 ;templatestyles src="Template:Blockquote/styles.css" / ;"I think a lot of that is determined by the success of the film. And I don't think that far ahead. The idea of reprising the role and going farther into that character is interesting to me... It would be exciting to watch a character progress or deteriorate. That's exciting for an actor. I thoroughly enjoyed playing Royce. Again, part of the attraction is I'm oddly drawn to material that affects me on an emotional level, and characters that are dealing with things that are challenging that I would question, that I'm not so familiar with. Royce has his emotional arc in this that most of the characters I've played don't come close to possessing. That's an interesting thing to cultivate."
In June 2014, Fox announced plans for a new movie, with Shane Black co-writing and directing, Fred Dekker co-writing and John Davis producing (without the involvement of Rodriguez). At the time, Black said the film is a sequel, rather than a reboot. In August 2015, Davis said the film would "reinvent the franchise." In November 2016, it was explained that since the plot takes place on Earth, the story will be more closely linked to the first two films. In December 2017, it was announced that while the film would acknowledge the events of "Predator" and "Predator 2", but before the events of "Predators".

"Heavy Metal" remake.
