The Guardians Volume 3 is released, it'll be the sixth series in the MCU to become a trilogy, and it'll be far from the last in the franchise to pull that off too.

But not every movie series gets that privilege, and there are tons of great two-movie series that deserve a third film. Redditors have vouched for so many series to get the trilogy treatment, and whether they'll ever happen or not, the s make some great arguments.

Top Gun (1986)

Redditor Top Gun: Maverick, there must be talks amongst studio heads at Paramount about a potential sequel. The newly released movie massively overperformed at the box office, making over $1 billion worldwide.

Maverick could be a ing of the torch, as the threequel could follow Rooster (Miles Teller), who was introduced in the sequel and quickly became a fan favorite. Teller himself has spoken about a potential sequel. The actor explained that he has spoken to Tom Cruise about a potential follow-up, simply noting, "I've been having some conversations with him about it. We'll see."

The Raid (2011)

Where The Raid nailed it three years earlier. The movie and its sequel are some of the most impressively violent action movies of the 2010s, and K9sbiggestfan wants to see a third installment. The Redditor its, "There isn't an obvious need for a third, it's just the first two are so good and I want more."

According to a remake of the original movie is in development with Michael Bay producing.

National Treasure (2004)

 Book of Secrets was released over 15 years ago.

The action and adventure in the movie are so much fun, but, unfortunately, Cage himself told Redditors he is no longer involved in the series. A National Treasure Disney+ series is in production, but it might not be the same without Benjamin Franklin Gates leading the adventure.

Tron (1982)

Redditor Tron: Legacy, there could be a sequel to the 2010 movie, but fans could be waiting another couple of decades for it.

However, even then, it's still massively unlikely, as the franchise has now underperformed twice. Not only did the original film struggle at the box office, but Tron: Legacy didn't do the numbers that Disney wanted either. To invest another couple hundred million dollars in a franchise that hasn't once been successful isn't exactly a smart financial decision.

Conan The Barbarian (1982)

While Arnold Schwarzenegger is best known for playing the T800 in Conan the Barbarian and its sequel, Conan the Destroyer. Damienkarras1973 wants a threequel more than anyone else, exclaiming, "King Conan!"

A third movie had been in development for years, even as recently as in the 2000s. It's one of Logan-like swan song.

21 Jump Street (2012)

It's hard to believe that 22 Jump Street, and the film was so successful that it comes as a shock that a third movie never arrived. Ok-bookkeeper-3999 is more surprised than anyone, asking, "Seriously, how did this not happen?"

Another sequel could ruin the gag at the end of the second movie, which essentially jokes that all franchises are run into the ground, as literally dozens of sequels and even tie-in video games are hinted at. But there's just so much potential for the series to continue. There were plans for a Jump Street/Men In Black crossover movie, which is too perfect to waste.

Wayne's World (1992)

The original hinted at an Austin Powers fourquel, but Ho7mes would rather see the Wayne's World series get rounded out with a trilogy. The Redditor comments, "I'd like to see a Wayne's World 3. 1 and 2 still hold up."

Given that the music landscape has drastically changed in the 30 years since the original movie, there are so many easy jokes to make that the threequel almost writes itself. Whether it's commenting on the way music is consumed through streaming services, the way MTV is more about reality shows than music videos, or popular music itself, Wayne and Garth's take on it all could be hilarious and even insightful.

The Mask Of Zorro (1998)

The character did come close to getting a third outing, but it was a much more unorthodox approach. Quentin Tarantino had planned to make the crossover movie Zorro and Django, which would have seen the two characters work together as bounty hunters. The celebrated director even pitched it to Banderas, who was totally on board. It's a fantastic idea, and the reason it was canned was that, according to co-writer Jerrod Carmichael, the movie would have cost $500 million to make.

Ace Ventura: Pet Detective (1994)

Redditor Sonic the Hedgehog movies, it's a surprise that there hasn't been any word on some sort of legacy sequel.

But if fans take Carrey's word for it, the actor is retiring from movies for good. That means that not only will there be no Ace Ventura 3, but he won't return as the Eggman for when they announce retirement plans, and even Cameron Diaz is returning this year after announcing her retirement in 2014.

Blade Runner (1982)

Wallace looks up in Blade Runner 2049

 Blade Runner 2049 teased so much more story, noting, "You can clearly tell plot points in Blade Runner 2049 were set up for a 3rd film (Wallace is still around, and the Resistance was hinted at)."

However, just like the Tron franchise, the Blade Runner series is zero-for-two when it comes to box office performance. Both movies are considered box office bombs, but as the two films come with enormous amounts of prestige and have a large fanbase, it could still happen. The sci-fi series could have a perfect final movie in a trilogy, as it could culminate in an epic final battle between the resistance and the humans.
