Development

The project emanated from Ali Soufan and Lawrence Wright's realization that both of them were fielding offers from various studios and production companies regarding the rights to their books about the lead-up to the September 11 terrorist attacks. The pair met with filmmaker Alex Gibney, who had already adapted Wright's one-man show, My Trip to Al-Qaeda and book Going Clear for HBO. Wright said about the collaborations with Gibney, "He's a documentarian, and he understands the importance of truth. We’ve been in the trenches. I came to trust him, and that's what I wanted — someone I felt could handle and negotiate these really difficult moral questions." Following that partnership, the team began to interview potential showrunners. They soon landed on screenwriter Dan Futterman after one meeting, and then decided to work on their pitch for the series.^[3] After refining their pitch, they approached HBO, Netflix and Amazon with the project. As a courtesy, they also reached out to Hulu without really placing them into consideration due to the perception of the streaming service as merely a place to stream episodes of network television shows. However, during their meeting with Hulu they were offered a straight-to-series order, an abbreviated development process, a promise not to cave under pressure from the federal agencies portrayed in the series, and the largest financial commitment of any service or network they had previously met with. It was due to these terms and conditions that the producers ultimately decided to sign with the company.^[4]

During pre-production, producers spent months doing exhaustive homework. This involved interviewing the real-life counterparts of the characters they were bringing to life, including Ali Soufan and his wife; former National Security Council chief counterterrorism adviser Richard Clarke; former and current members of the FBI's I-49 squad; and former members of the CIA.^[5] Futterman has mentioned that in addition to adapting Wright's book, the series also drew from Soufan's book The Black Banners: The Inside Story of 9/11 and the War Against al-Qaeda and the 9/11 Commission Report.^[6]

In September 2016, Hulu ordered The Looming Tower to series from Legendary Television with executive producers including Alex Gibney, Dan Futterman, and Lawrence Wright. It was announced that the limited series would consist of ten episodes and premiere in 2017.^[7] It was later reported that Craig Zisk was also an executive producer for the series and would be directing as well.^[8] Ultimately, five different directors were chosen to helm the series' ten episodes: Zisk, Michael Slovis, John Dahl, Ali Selim and Alex Gibney. The show's first episode was directed by Gibney, episodes six and seven were directed by Slovis, and episodes eight, nine, and ten were directed by Zisk. The series' story requires multiple international locations with the first five episodes having scenes that are set in seven countries and ten cities. Early on in the development process, Zisk and Gibney went on several international location scouting missions, in order to give their fellow directors options to pick from for filming.^[9]

Casting

In January 2017, it was announced that Tahar Rahim was cast in one of the series' lead roles as Ali Soufan.^[10] In February 2017, Michael Stuhlbarg and Bill Camp were announced as series regulars and cast as Richard Clarke and Robert Chesney, respectively.^[11] In March 2017, Jeff Daniels was cast as John O’Neill.^[12] Also announced that month were the castings of Sullivan Jones, Virginia Kull, Louis Cancelmi, Peter Sarsgaard, and Wrenn Schmidt and Ella Rae Peck as series regulars.^[13][14][15] In May 2017, Alec Baldwin was cast as George Tenet in a guest role.^[16]

After being cast as the late O’Neill, Jeff Daniels struggled on how to approach playing the role. He ultimately credits significant research he did involving speaking with those who knew O'Neill. At one point, he spent an evening at a bar in Lower Manhattan with ten of O’Neill's colleagues, who'd worked with him for years. He commented, "I had a great meeting with those guys, walked out to the corner, turned to get a cab and there's the World Trade Center. To feel him, you need the spirit of what John is fighting for."^[5]

Filming

The series began filming on May 3, 2017 in New York City^[16] and it was expected that shooting would take place in a number of locations around the world.^[17] Ultimately, the production lasted six months and sprawled across three continents and six countries.^[5] Various places stood-in for the locales in which the story actually took place. For instance, scenes set in Yemen were filmed in Morocco, and drone and car travel shots of Pakistani landscapes were used to evoke Afghanistan. Johannesburg, South Africa served as the production base, and was where the bulk of filming took place. The city possessed the "visual variety" that the producers were seeking, and doubled for various places including Nairobi, Tanzania, England, Albania, and Las Vegas, Nevada.^[9] While there was an initial push to shoot the production all in South Africa, Zisk argued for filming the back half in Morocco. In August 2017, filming took place at the River Café in Brooklyn.^[9]

Production designer Lester Cohen credits Wright's and Gibney's list of contacts and the production's research team for allowing him to gather the material needed to recreate various settings. During the design period, a set dresser shared photos of his tour in Afghanistan and an art coordinator's daughter dove into the newspaper archives in Nairobi to help re-create the bombing site of the 1998 embassy attacks. Those details informed the design of the huge rubble pile that shut down the central business district in Cape Town for weeks. Also, as much of the story that takes place in the United States occurs in offices, practical sets were built, including Alec Station and the FBI office in New York.^[5]

Marketing

On December 19, 2017, Hulu released the first preview of the series through a collection of images and a "first-look" video featuring interviews with the cast and crew.^[18] On January 11, 2018, Hulu released the first official trailer for the series.^[19]

The Looming Tower was released on Blu-ray and DVD on September 18, 2018. The set includes four behind-the-scenes featurettes and audio commentaries on the premiere and finale episodes.^[32]

Critical response

The Looming Tower was met with a positive response from critics. On the review aggregation website Rotten Tomatoes, the series holds an 88% approval rating with an average rating of 7.4 out of 10 based on 60 reviews. The website's critical consensus reads, "Well-acted and powerfully written, The Looming Tower delivers gripping counter-terrorism drama rendered even more soberingly effective through its roots in real-life events."^[33] Metacritic, which uses a weighted average, assigned the series a score of 74 out of 100 based on 25 critics, indicating "generally favorable reviews."^[34]

The Washington Post's Hank Stuever praised the series for its "coolly fascinating pace and tenor" and commented that "Tahar Rahim gives a smart and sincere performance as Ali Soufan, a Muslim American agent on O’Neill's squad."^[35] The Hollywood Reporter's Daniel Fienberg offered the series praise saying, "The Looming Tower demands a hasty combination of faith in the storytellers and half-forgotten knowledge of the history. Absent that, the series is essentially like a well-shot, brilliantly cast, fast-moving season of Homeland, which is better than the actual current season of Homeland."^[36] In a positive review, Variety's Maureen Ryan said that the show was an "accessible, illuminating series that does not downplay the petty and tragic elements of the tale."^[37] Time's Daniel D'Addario commended the show as "a series that's both gripping and relevant. It succeeds, with a project that restages the years before Sept. 11 and tells a darkly ironic story about the fecklessness of government."^[38] In a more negative review, Collider's Chris Cabin criticized the series calling it "a middling act of didacticism, an attempt to pass off facts as insight and characters as little more than the sum of their intellect. Rather than tracing the complicated personalities and ludicrous dick-measuring contests that led to Al-Qaeda carrying out the biggest terrorist attack in American history, Gibney, Wright, and the rest of the creative team boil down the personal drama to little more than a series of arguments and discussions in offices at varying volumes."^[39]
