Anthony Mackie and Sebastian Stan reprise their respective roles as Sam Wilson and Bucky Barnes from the film series, with Emily VanCamp, Wyatt Russell, Erin Kellyman, Julia Louis-Dreyfus, Danny Ramirez, Georges St-Pierre, Adepero Oduye, and Daniel Brühl also starring.

The acting, visuals, and Wilson's character arc were praised, but it was deemed to be weaker than the previous episodes and some felt it was an unsatisfying conclusion with an abrupt characterization shift for John Walker (Russell).

Wearing his new Captain America suit from the Wakandans, Sam Wilson flies to New York City to save the Global Repatriation Council (GRC) from the Flag Smashers' attack.

The remaining Super Soldier Serum-enhanced Flag Smashers are sent to the Raft prison, but are killed when their transport vehicle is bombed by Helmut Zemo's butler Oeznik.

[4] Kari Skogland was hired to direct the miniseries a month later,[5] and executive produced alongside Spellman and Marvel Studios' Kevin Feige, Louis D'Esposito, Victoria Alonso, and Nate Moore.

[8] While many described John Walker's ending as "getting off easy",[9][10] Spellman did not believe this was the case, noting how his career had been destroyed and for someone in the military, "to get anything other than an honorable discharge, that's a big deal".

[11][10] Executive producer Nate Moore said that the team did not choose to make Walker the main antagonist of the episode, but have him dispose of his fake shield to instead save the Global Repatriation Council (GRC) members from the Flag Smashers.

The team wanted to show a human moment as well as the superpower of the new Captain America, which "as a Black man, [Wilson] is forged in an identity that is rooted around struggle".

Spellman enjoyed the line in which Bradley told Wilson that he's no "Malcolm, Mandela, or Martin", and credited it to the writers' room consisting of Black people.

[16] Following initial plans to debut Wilson's Captain America costume in "Truth", the creative team instead opted to first feature it while he was saving GRC members on the ground and then flying into the building.

[17] Speaking about the mid-credits scene, Spellman said that from it, the audience would know "exactly what doors just got opened to an expanded universe",[18] with VanCamp noting Carter "has a much bigger plan and it's not for the greater good like it used to be".

[22] The episode stars Anthony Mackie as Sam Wilson / Captain America, Sebastian Stan as Bucky Barnes / Winter Soldier, Emily VanCamp as Sharon Carter / Power Broker, Wyatt Russell as John Walker / U.S.

[23][24]: 44:12–44:42  Also appearing are Carl Lumbly as Isaiah Bradley, Amy Aquino as Christina Raynor, Desmond Chiam as Dovich, Dani Deetee as Gigi, Indya Bussey as DeeDee, Renes Rivera as Lennox, Tyler Dean Flores as Diego, Elijah Richardson as Eli Bradley, Chase River McGhee as Cass, Aaron Haynes as AJ, Ken Takemoto as Yori, Miki Ishikawa as Leah, Rebecca Lines as Atwood, Jane Rumbaua as Ayla, Salem Murphy as Lacont, Nicholas Pryor as Oeznik, and Gabrielle Byndloss as Olivia Walker.

[22] The last scene of the episode, in which Wilson and Barnes stand together at the docks, was filmed during the first day of production, with Mackie calling it a "beautiful camaraderie to start the show".

As reshooting it was impractical at the time, the VFX team fixed this issue by creating a small landing space for Wilson that featured white light.

They also decided to include additional shots of him throwing his shield to recreate a comic book cover-shot, as the team felt it made the entrance "look as good as possible".

Additional refinements were done by inserting elements of flora, set dressings, bridges, detailed and realistic rendering of environments, and modelling local watercraft traffic across the scenes.

According to Imageworks VFX supervisor Chris Waegner, the pit's depth was manipulated across various shots to convey a "heightened sense of danger and help facilitate the stunts".

[54] Nielsen Media Research, which measures the number of minutes watched by United States audiences on television sets, listed The Falcon and the Winter Soldier as the most-watched original series across streaming services for the week of April 19 to 25, 2021.

The site's critical consensus reads, "While "One World, One People" delivers a fitting ending for Sam, its rush to wrap The Falcon and The Winter Soldier's many threads may leave some fans wanting—and wondering if there will be a second season to help make amends.

[57][59][60] Rolling Stone's Alan Sepinwall felt that the series "crashes and burns" with "One World, One People", stating, "It's a mess in nearly every way, with even the parts that work feeling rushed and unearned, carried largely by the performers rather than the storytelling".

Sepinwall described it as "a particular bummer" and "a visual muddle" since Wilson's debut as Captain America should have been "a triumphant moment that showcases how good Sam is in the role".

The "most insufferable part of this episode" was Wilson's "wannabe Aaron Sorkin lecture" that had "a weird racial element" to it, since it continued the storytelling trend of the series to explain things rather than showing.

Holub believed this was one of the reasons the Flag Smashers did not connect with the audience since their motivations were based on "monotonous exposition and dialogue that just stated facts rather than showing us story".

[61] Writing for IGN, Matt Purslow gave "One World, One People" a 5 out of 10, believing the episode "struggle[d] under the weight of the many threads" the series had to conclude, resulting in a rushed and unsatisfying finale.

Purslow criticized the pacing of the episodes, and felt that the action at times got in the way of more deserving plot elements such as greater exploration of Morgenthau and Walker, who both had "underwhelming parts to play" in the finale.

[62] At the 73rd Primetime Creative Arts Emmy Awards, Matthew Wood, Bonnie Wild, James Spencer, Richard Quinn, Steve Slanec, Kimberly Patrick, Teresa Eckton, Frank Rinella, Devon Kelley, Larry Oatfield, Anele Onyekwere, Dan Pinder, Ronni Brown, and Andrea Gard were nominated for Outstanding Sound Editing for a Comedy or Drama Series (One-Hour) for their work on the episode.
