Kleber Mendonça Filho, the director of 'The Secret Agent', has released a video showcasing the special effects that were implemented in his film. In the video, he compares scenes before and after the addition of these digital enhancements, providing an insight into how technology can dramatically alter visual storytelling. He expresses admiration for the contributions from French companies McMurphy and Brom, as well as the Dutch firm Lads, which played significant roles in the final look of the film.

The specific scene highlighted features the protagonist, played by Wagner Moura, leaning out of an old building's window to gaze at the Duarte Coelho bridge that links the neighborhoods of Boa Vista and Santo Antônio in Recife, Pernambuco. The special effects aimed to recreate the aesthetic of the bridge as it appeared in the 1970s, the time period in which the film is set. Among the enhancements were digitally added vehicles from that era, which helped to immerse viewers in the historical context of the narrative.

Mendonça Filho takes particular delight in how the original flooring of the Duarte Coelho bridge was restored digitally, affirming the importance of authenticity in setting the film's atmosphere. He also shares an amusing detail from the video that includes the digital creation of a two-headed cat that appears in the film, further showcasing the creativity and innovation brought to the project through modern special effects techniques.
