Born and raised in Greenville, Michigan, Mahan developed an early fascination with monsters and creatures through classic Universal horror films and Toho’s Godzilla series. While attending Greenville High School, he began experimenting with stage makeup and prosthetics, drawing knowledge from library books and self-guided practice. After graduating in 1981, he moved to Hollywood to pursue a career in special effects, enrolling at the E.I. School of Professional Makeup to further develop his skills.

Mahan’s professional breakthrough came in 1983 when he was hired by Stan Winston Studios to work on The Terminator. This collaboration marked the beginning of a 25-year career at one of the most influential effects studios in film history. At Stan Winston Studio, Mahan rose to become a lead art department supervisor and creature effects specialist, contributing to landmark productions such as The Terminator and Terminator 2: Judgment Day, Aliens, Predator and Predator 2, The Lost World: Jurassic Park, and many others that helped establish practical effects as a cornerstone of blockbuster filmmaking.
“The Terminator was like 8 years of concentrated film school, in one 5-month period… every lesson I’ve learned from that film, until today, has pretty much been retained.”

One of the defining moments of Mahan’s career came with Iron Man (2008), where he and his design team created the practical suits worn by Robert Downey Jr., as well as a fully realized animatronic Iron Man suit standing ten feet tall, weighing over 800 pounds, and operated by five puppeteers. The work earned Mahan and his team an Academy Award nomination for Best Achievement in Visual Effects. His involvement in Iron Man led to continued collaborations across the Marvel Cinematic Universe, including Iron Man 2 and Iron Man 3, Captain America: The Winter Soldier, Guardians of the Galaxy Vol. 2, Captain Marvel, Avengers: Infinity War, and Avengers: Endgame.
“In the perfect world, or in the real industrial world, you’ll build a prototype and then you’ll build it again. And you’ll probably build it one more time before you make it where it you’re happy with it. In the film world, you get X amount of time and resources and you really are racing to the finish line with the one piece. So you don’t have a lot of time to do a lot of experimentation. What’s great about doing a sequel is you can get all the brains together in one room to talk about what worked and what didn’t work before—let’s be very scientific about it.”
Following the death of Stan Winston in 2008, Mahan, together with longtime collaborators John Rosengrant, J. Alan Scott, and Lindsay MacGowan, founded Legacy Effects, a studio dedicated to continuing Winston’s legacy while pushing practical effects into new technological territory. Under Mahan’s leadership as co-owner and FX supervisor, Legacy Effects has become one of Hollywood’s leading character design, makeup, and animatronics studios, known for seamlessly integrating practical and digital effects.
Through Legacy Effects, Mahan has supervised or contributed to more than 75 feature films and television projects, including Pacific Rim and Pacific Rim: Uprising, Godzilla: King of Monsters, Jurassic World, The Jungle Book, The Revenant, and Guillermo del Toro’s The Shape of Water, which won the Academy Award for Best Picture. His work can also be seen prominently in major television productions such as The Mandalorian and Obi-Wan Kenobi, as well as large-scale franchise films including Avatar: The Way of Water. He has also received another Oscar nomination for last year’s Alien: Romulus.
