What will Once Upon A Time In Hollywood, is set to hit cinemas on July 26, 2019, but Tarantino doesn't have anything officially in the works to follow it up with. That's not too surprising, because he often has a number of different projects that he's considering at any one time.

Once Upon A Time In Hollywood is being billed as not only Kill Bill Vol 1 & 2 as just one single movie.

Still, with whatever he does next possibly being the last movie he makes - until he states it isn't - then there's going to be a lot of speculation as to what movie Tarantino decides to do next. His career includes a long list of unmade projects, while he's been linked with some big films in recent years, making these the most likely follow-ups to Once Upon A Time In Hollywood.

Star Trek

Quentin Tarantino Star Trek Will Be Pulp Fiction in Space

Quentin Tarantino's Tarantino was first reported to be working on Star Trek back in 2017, when it was revealed that he and J.J. Abrams had made a pitch for a new film, which Tarantino would direct and Abrams would produce, with Mark L. Smith later being hired to write the screenplay.

Tarantino has given various updates on Star Trek since then. It was reported in late-2017 that The Revenant, has been completed, but that Tarantino still needs to "weigh in on it." It makes sense that he hasn't been able to give it too much attention, since he's been busy on Once Upon A Time In Hollywood.

With that film about to release and Tarantino on the press circuit, however, more details about his Star Trek movie have started to come out. Star Trek movie will be like Pulp Fiction in space, saying: "That Pulp Fiction-y aspect, when I read the script, I felt, I have never read a science fiction movie that has this sh*t in it, ever."

With Tarantino having been so open about Star Trek - as well as being a Star Trek 4. If Tarantino's Star Trek doesn't happen, he does have some other options.

Kill Bill 3

Uma Thurman as The Bride in Kill Bill Vol 1 and Vol 2

Kill Bill 3 is something Quentin Tarantino has been talking about the possibility of ever since Kill Bill Vol 2 was released back in 2004. Speaking to Entertainment Weekly at the time, he said: "Oh yeah, initially I was thinking this would be my Dollars Trilogy. I was going to do a new one every ten years. But I need at least fifteen years before I do this again. I've already got the whole mythology: Sofie Fatale will get all of Bill's money. She'll raise Nikki, who'll take on The Bride. Nikki deserves her revenge every bit as much as The Bride deserved hers. I might even shoot a couple of scenes for it now so I can get the actresses while they're this age."

Tarantino has given updates on Kill Bill 3 at various intervals over the years. At one point he was set to make a prequel anime, and then in 2009 he suggested it was going to be his next film, to release in 2014, 10 years after Kill Bill Vol. 2. That never materialized, and Tarantino has largely been non-committal since then. When details about Tarantino's on-set behavior towards Uma Thurman were revealed, it then looked like Kill Bill 3 was never going to happen, but it now seems like it might be back on the cards.

While on the press tour for Once Upon A Time In Hollywood, Tarantino spoke about Kill Bill 3 happening, saying: “Me and Uma have talked about it recently, frankly, to tell you the truth. I have thought about it a little further. We were talking about it literally last week. If any of my movies were going to spring from my other movies, it would be a third ‘Kill Bill.’” So maybe there is a chance of Vernita Green's daughter getting revenge on the Bride after all.

Less Than Zero

Quentin Tarantino has long been linked with adapting Brett Easton Ellis' debut novel Less Than Zero, although anything more concrete is yet to materialize. Tarantino is a huge fan of Ellis and the book itself, which has the kind of challenging subject matter you could imagine the director wanting to sink his teeth into. Published in 1985, Less Than Zero tells the story of a young, rich college student who returns home and enters into a tragical spiral of drugs and sex.

Less Than Zero was adapted into a film in 1987 starring Robert Downey Jr. and James Spader, but it was only loosely based on the source material and Ellis himself wasn't a fan. Tarantino's friend Roger Avary directed an adaptation of another Ellis novel, Rules of Attraction, in 2002, which is where the rumors of Tarantino's interest started. Ellis himself said in both 2010 and 2012 that Tarantino had been trying to adapt Less Than Zero, although obviously to no avail. It's been a long time since then, but this would be an interesting shift in direction for Tarantino at this point in his career, and if it's a serious ion project then he could try again to make it happen.

Killer Crow

Inglourious Basterds

Inglourious Basterds in the late-90s, but when he couldn't make the ending work he dropped it to focus on directing Kill Bill instead. When he returned to the project he went back to his initial draft and trimmed it right down, resulting in the finished product that focuses on the titular Basterds.

That meant Tarantino cut a lot of material from the original Inglourious Basterds script, however, which he has since said could work as a film in its own right, going by the working title Tarantino last discussed Killer Crow back in 2015, so it does seem like he might've dropped it, but with plenty of material already in place it would be an easier one for him to revisit as his next movie.

Django/Zorro

Django back to back with Zorro

While no movie sequel to Django/Zorro is a seven-issue comic book run that picked up after the events of Django Unchained. After settling Broomhilda safely in Chicago, Django goes back out on the road, where he meets the legendary Zorro, ing him on a mission to free indigenous people from slavery.

It sounds like the kind of wild idea that might be confined to a comic book, but Django/Zorro movie is at the very least moving forward, and if Tarantino takes a more active role in its development or gets a script he loves, then there's a possibility he'll want to be the one who makes it.

Other Movies Tarantino Could Make Next

Pulp Fiction spin-off centering on Vic & Vincent Vega, played by Michael Masden and John Travolta respectively. Given how long it's been, however, with both actors aging out of what would've been a prequel, Double V Vega now seems unlikely to ever happen.

Another oft-discussed Tarantino project that never happened is an adaptation of Elmore Leonard's Once Upon A Time In Hollywood releasing, it hopefully won't be too much longer before we find out what Quentin Tarantino's next movie is.
