The middle pieces often decide the best-remembered stories between the beginning and finale – the journey of the characters' trials and errors and where the audience comes to learn about them most intimately. The middle film can fall apart if the journey from inciting incident to catharsis is lackluster.

These films took the daunting challenges of a sequel and passed with flying colors – and future creators should take note.

The Two Towers(2002)

The obvious poster child is evident for a reason. In no small part credited to the brilliance of the source material,Peter Jackson’sinterpretation ofJ. R. R. Tolkien’sThe Two Towersexcels at every high expectation set on the shoulders of sequels. Deeper character development? Check. Deeper world? Check. Consistency? Check.

Without losing sight entirely of the whimsy ofFellowship of the Ring,Two Towersdips its toe into the epic culmination of a Middle-Earth spanning fantasy war with theperfect balance of grit and sincerity. Bolstered by stellar performances, groundbreaking special effects, and a score as complex as Tolkien’s lore,Two Towersstands the test of time as the one sequel to rule them all.

Kung Fu Panda 2(2011)

DreamWorks Animation’scatalog boasts many divisive films on a broad spectrum, from the biblical scale ofThe Prince of Egyptto flops likeShrek the Third. The studio’s action-packed tale of a panda who learns kung fu began its legacy surpassing all expectations of being a good film based on its premise alone.

The sincerity of the original’s message, that “there is no secret ingredient” to be unique, was further showcased in its sequel, giving protagonist Po a new, personal villain,more vivid animation, stunning music, and a heavy lesson in letting go of the past.Kung Fu Panda 2delivered a darker, nuanced sequel still bountiful in classic DreamWorks jokes and gags. It remains one of the studio’s tentpole franchises due in no small part to the strength of its middle segment.

Captain America: The Winter Solider, Bucky Revealed

Captain America: The Winter Soldier(2014)

Of all the films of the MCU,Winter Soldierboats an impressive level of nuance, thrilling and brutal fight choreography, and a chilling conspiracy that flipped the universe on its head. Coming off the heels of a romp through 1940s America’s campiest propaganda,Winter Soldierbegan Steve Roger’s (Chris Evans) break from his naïve trust in S.H.I.E.L.D and wore away at the golden boy hero.

The Empire Strikes Back, Luke vs. Vader

Compared to the bombast of the other Marvel films,Winter Soldierdistinguishes itself as a spy thriller that just so happens to star a super soldier and his not-so-deceased, brainwashed best friend as the villain. UntilScarlett Johanssongot her solo Black Widow film seven years later, she and Evans had their finest hour here as the perfect team.

The Empire Strikes Back(1980)

As obvious asTwo Towers, middle movies are generously dubbed the “Empire Strikes Back” of their franchise for a reason.A New Hopewas the tale of a farm boy bestowed a magic sword by a mysterious wizard to take up arms and fight the evil empire, reskinned as a jaw-dropping space opera.

Empire Strikes Backgave audiences richer backstories for its heroes and villains, the temporary loss of a beloved character, and set the Rebel Alliance at even steeper odds. All that has been said aboutEmpirehas been said in excess. It remains the gold standard even 40 years after its release.

The Dark Knight, The Joker (Heath Ledger)

The Dark Knight(2008)

What more can be said aboutChristopher Nolan’sThe Dark Knight? Juggling a wickedly complex story that stops for nothing, two ofBatman’smost infamous rogues, and beyond stellar performances fromHeath Ledger,Gary Oldman,Christian Bale, andAaron Eckhart,The Dark Knightdeserves all its accolades.

In delivering the age-old battle for the soul of Gotham,The Dark Knightis Batman at near its very best.

Spider-Man 2(2004)

Peter Parker has hit the live-action big-screen three times with a sequel film, and of those three,Sam Raimi’stake on Doc Ock (Alfred Molina) remains one of cinema’s best bittersweet villains.Set two years after the first film,Parker (Tobey Maguire) struggles to balance his two identities and jeopardizes both when his worlds collide.

What sets Raimi’s sequel apart fromThe Amazing Spider-Man 2andFar From Homeis a combination of Maguire and Molina’s sincere and stellar performances. A hero is often as great as their villain, and Doc Ock’s reluctant villainy matches Peter Park in depth at every turn more than, say, Malekith, from a much less worthy middle Marvel film.

Back to the Future Part II(1989)

Where they’re going, they don’t need roads.Back to the Future Part IIwent the only way a trilogy about time travel could go. The first film sent Marty McFly (Michael J. Fox) to the past to grapple with his then-young parents. Its sequel drops him in thenot-so-distant futureto save his kids.

An ill-fated attempt to secure a glorious future with the sports almanac upends Marty’s life. The stakes don’t necessarily have to be higher, only as intense or more. The threat of the warped hellscape Marty’s butterfly effect causes makes for an exciting next chapter in an already fantastic story.

The Godfather: Part II(1974)

One of the first “Part 2’s” in western cinema,Francis Ford Coppola’sepic mob drama doubles as a sequel and a prequel. The film develops its principal characters, Vito and Michael Corleone (Robert DeNiroandAl Pacino), and juxtaposes their lives as gangsters and the Corleone mob.

It enriches the original work with every performance, effortlessly answers every lingering plot thread from its predecessor, and expounds upon untread territory more than deserving of being one of the best films of all time.

Though technically not a trilogy with five films to the franchise, Disney’sPirates of the Caribbeanis so often regarded as complete withAt World’s End. With award-winning special effects,Dead Man’s Chestis a classic treasure hunt wrapped inside a McGuffin withone of Disney’s best live-action villainsat the center of it all.

Bill Nighy’sgripping performance as Davy Jones brings just the right amount of terror and charisma to the captain of a crew of immortal fish people that could have so easily been campy and static. The buildup to his reveal and the turmoil of his character, Hans Zimmer’s score, and the race to find the key and the titular chest remains one of Disney’s best action adventures that’s endlessly rewatchable.

For A Few Dollars More(1965)

Perhaps not as instantly recognizable as its predecessor,A Fistful of Dollars, or its famous successor,The Good, the Bad, and the Ugly,Sergio Leone’sDollarsTrilogy wouldn’t be complete without its middle work. FollowingClint Eastwoodas Monco, The Man With No Name, a bounty hunter at odds with rival bounty hunter Col. Douglas Mortimer (Lee Van Cleef), the two set aside their differences to hunt down an escaped Mexican outlaw.

For a Few Dollars Moreis exactly what it needs to be; equally exciting and groundbreaking in its production and development of Eastwood’s character helped define the collective idea of what the wild, wild West might have been.
