Summary

• Agents of SHIELD season 1 effectively prologued and epilogued Captain America: The Winter Soldier in real-time.
• The Winter Soldier crossover dismantled SHIELD's core premise, providing a compelling narrative for future seasons.
• Difficulties regarding scheduling, coordination, and development between film and television led to fewer MCU crossovers with SHIELD after The Winter Soldier event, making SHIELD's final season 1 episodes even more special and impressive.

Having recently rewatched Marvel's Agents of SHIELD, I still can't believe how well the first season's final episodes crossed over with Captain America: The Winter Soldier. Just over 10 years later, the ability to blend narratives between network television and a big-screen theatrical release is still one of the most impressive executions of connectivity within an interconnected universe such as the MCU. As such, it makes sense why there was never a similar crossover of equal size again before the dawn of the steaming Disney+ era.

Having aired for seven seasons between 2013-2020, Agents of SHIELD was just as much a part of the Infinity Saga as any MCU movie. Regardless of its apparent lack of canonicity in the current era, the first season's ability to not only reference but also be intrinsically affected by the movies required some amazing navigation from both Marvel Studios and television's Marvel Entertainment. To that end, I truly believe that the final episodes of Agents of SHIELD season 1 and its crossover with the events of The Winter Soldier is still one of the best moments in the early phases of the MCU.

Agents of SHIELD's Crossover With Winter Soldier Was MCU Connectivity At Its Finest

Providing The 2014 Movie With A "Real-Time" Prologue and Epilogue

Right off the bat, one of the most impressive elements of Agents of SHIELD's crossover with Winter Soldier was the scheduling. 10 years ago, Captain America: The Winter Soldier was released on April 4th, 2014. During that same month, Agents of SHIELD season 1, "End of the Beginning" aired on ABC on April 1st, just a few days beforehand. In the episode, Agent Phil Coulson and his team faced some serious distrust among their own ranks, all while seeds were being sown for The Winter Soldier itself.

This included Agent Sitwell leaving to board The Lumurian Star as he's featured in the opening scene of The Winter Soldier, as well as Agent Simmons' comments that SHIELD was scrambling to handle some sort of major crisis. As such, it effectively served as a prologue episode which helped provide additional context and background for the new MCU movie which fans could watch from home before leaving for the theater (all in the same week.) However, this preceding episode was nothing compared to the very next episode, "Turn, Turn, Turn", which released on April 8th, only a few days after The Winter Soldier's theatrical release.

The reveal in The Winter Soldier that Hydra had embedded itself within SHIELD naturally had massive ramifications for the Marvel show. As such, the episode immediately following the release of this MCU movie served as a key epilogue, showing how SHIELD agents began turning on each other due to justified mistrust and paranoia. It even saw Brett Dalton's Grand Ward being revealed as a member of Hydra, a core member of Coulson's team. Combined with footage from The Winter Soldier and a major appearance in the series' finale from Samuel L. Jackson's Nick Fury himself, a real-time MCU crossover such as this really hasn't happened since.

SHIELD's Final Season 1 Episodes Make Me Love Winter Soldier Even More

"We Are Not Agents of Nothing!"

I've always loved and deeply ired Marvel's willingness to fully dismantle the core premise of Agents of SHIELD by the end of its first season. The Winter Soldier effectively destroyed the entire infrastructure of SHIELD as it had been established in Marvel's first phase thanks to Hydra and Captain America's successfully exposing them to the world. In effect, this allowed SHIELD to become even more creative with future seasons, putting its agents into unknown territory as they fought to survive and rebuild, beginning with Fury making Coulson SHIELD's new director, a role he would hold onto for quite some time.

That said, The Winter Soldier is something I've always loved as well. Through SHIELD, viewers get to see the full scope of Hydra's infiltration, not just from the vantage point of Steve Rogers alone. It showed how individual agents were impacted by the hard truth that everything they'd fought for had long been corrupted by dark forces. Furthermore, appearances from the likes of Fury and Maria Hill also point back to The Winter Soldier, seeing how the show picks them up right where the movie left them before the credits.

Why Agents of SHIELD Did Fewer Crossovers Afterward

(It Was Really Hard To Pull Off)

Agents of SHIELD never stopped being connected to the rest of the MCU. Throughout its seven seasons, there were plenty of references made to characters and events seen in MCU movies, such as Coulson secretly being responsible for prepping Fury's Helicarrier in Avengers: Age of Ultron, or mentions of Thanos and the Battle of Wakanda in Agents of SHIELD season 5. However, they never did have another major crossover like they had in the first season with The Winter Soldier, partly because it was so hard to pull off.

As was later revealed in interviews with the cast and crew, it was quite a challenge keeping The Winter Soldier's Hydra reveal a secret. Scripts were largely redacted prior to shooting, and nailing the release of episodes with the movie's theatrical release was reportedly difficult enough that pulling it off a second time with future seasons was something that apparently proved too difficult. This does make sense, giving consideration to the actual writing and development of both the show and various movies ahead of time.

This ultimately explains why crossovers and connection points between SHIELD and the greater MCU became smaller and far less involved going forward, especially as Marvel Studios' production schedule massively ramped up. To that end, I do believe that the aforementioned challenges involved make what was achieved with The Winter Soldier even more impressive. It's a large testament to what made SHIELD so compelling to begin with, especially with its first few seasons.

I Won't Forgive Marvel Until Agents of SHIELD Is Canon Again

At Least Seasons 1-4

Unfortunately, it's recently been confirmed that Marvel Studios no longer considers Agents of SHIELD to be canon with the events of the main MCU timeline (Earth-616). This includes Winter Soldier's crossover episodes from the first season. However, there is some hope for SHIELD one day getting its canon status back thanks to Marvel's decision to make at least Netflix's Daredevil canon with the reintroduction of Charlie Cox's Daredevil and Vincent D'onofrio's Kingpin in more recent MCU movies and shows including Spider-Man: No Way Home, Hawkeye, She-Hulk, Echo, and soon the brand-new series Daredevil: Born Again.

All Marvel's Agents of SHIELD needs is a new MCU project to bring characters like Coulson or Daisy "Quake" Johnson back into the fold, providing a similar logical means to make the show canon once more. Many, including myself, had hoped that that project would have been Nick Fury's Secret Invasion series with its heavily-rumored Quake cameo. At any rate, I'd even settle for a compromise where only the first four seasons of SHIELD become canon. After all, Agents of SHIELD seasons 5-7 were largely set in different timelines anyway (and hardly had any major impact on the rest of the MCU at large).
