Ongaro was born in Lugano, Switzerland, and holds Swiss, Italian, and American citizenship.14 He studied design at the School of Design in Milan, Italy, where he first encountered computers as tools for creating photorealistic 3D renderings, initially applied to architectural visualisation.1
Ongaro began working in visual effects in 1998 in Switzerland, applying computer skills to post-production for film, television, and opening sequences.1 He subsequently relocated to Milan, joining Digitalia Graphics, the first Italian production company to work directly with film negatives.15 After approximately five years there, he relocated to northern California in April 2004 following an offer from ESC Entertainment, the VFX studio behind The Matrix trilogy.1 His first Hollywood production was Paramount's Constantine (2005), starring Keanu Reeves.6
After Constantine, Ongaro joined DreamWorks Animation, where he remained for roughly eleven years as an effects artist and supervisor. His credits during that period include Madagascar (2005), Over the Hedge (2006), Shrek Forever After (2010), Turbo (2013), and Kung Fu Panda 3 (2016).6
In 2015, Ongaro joined DNEG at their Vancouver facility, transitioning into the role of production VFX supervisor on large-scale live-action films.2 His DNEG credits include Ant-Man and the Wasp (2018), Men in Black: International (2019), Ghostbusters: Afterlife (2021), The Adam Project (2022), Godzilla x Kong: The New Empire (2024), and Captain America: Brave New World (2025).6
Ongaro came onto Ghostbusters: Afterlife as overall VFX supervisor when the original supervisor, Sheena Duggal, departed to supervise Venom: Let There Be Carnage.2 He joined just before principal photography, missing the prep phase. He described the assignment as a once-in-a-lifetime opportunity, having grown up with the 1984 film, and his approach throughout was shaped by Jason Reitman's stated goal of making a love letter to the original.2
Scale and vendors. Ongaro oversaw approximately 1,100 VFX shots.27 The lead vendor was DNEG, with MPC, Crafty Apes, and Proof also contributing.2 He used cineSync to coordinate creative reviews and annotations across the distributed teams, stating: "I lived on cineSync! We used cineSync for every review. It made it easy to give creative notes, make annotations, and get Ghostbusters: Afterlife's shots where they needed to be."7
Digital Egon Spengler. The most technically complex sequence was the digital resurrection of Egon Spengler, recreating the likeness of Harold Ramis, who died in 2014.2 Because no body scan existed, the team built the character entirely from reference frames drawn from the 1984 film and its sequel.28 Actor Bob Gunton provided the physical performance on set; only the neck and above were replaced in post, with Gunton's body retained throughout.28 The facial animation at MPC was driven by animator artistry rather than motion capture, using outtakes from the original films as an expression library.2 Ongaro and the team tested the reconstruction by replacing Egon in an elevator scene from the 1984 film and presented the result in black and white to director Jason Reitman and Ivan Reitman before any shots were committed to the film.2
Terror Dogs. On-set practical half-body puppet builds were used for stationary or close-contact scenes, including the Walmart introduction and the sequence where a Terror Dog leaps onto a car.28 For running and action sequences that exceeded the puppet's capability, CG models took over. The practical puppet was scanned to produce a one-to-one CG match, preserving the texture and silhouette of the physical prop across the transition.2
Proton beams. Ongaro developed an updated version of the proton beams that maintained the visual language of the hand-drawn optical printing effects from 1984 while incorporating modern complexity: added noise layers and richer visual detail within the same general look.2 The goal was for the beams to read as continuous with the original to a viewer who knew both films well.2
Gozer. The sequence featuring Gozer the Gozerian, portrayed by Olivia Wilde, involved a full body replacement to alter proportions, making the costume appear translucent and adding supernatural energy effects layered over the performance.2
Ecto-1 and other elements. Ongaro supervised VFX on the Ecto-1 sequences, including cornfield driving shots and stunt-replacement work on jump sequences, as well as the Muncher character and the miniaturised Stay Puft Marshmallow Men.27
Ongaro holds three citizenships: Swiss, Italian, and American, reflecting his origins in Switzerland and his extended professional life in Italy and the United States.1
