Lee McNair began his career in animation in 2002 after graduating from the Computer Animation program at Sheridan College near his hometown of Toronto, Ontario. Starting in television, he soon transitioned into Feature Animation and eventually into Visual Effects, continually balancing his passion for both specialities.

Before joining Industrial Light & Magic (ILM), McNair was Lead Animator at Digital Domain, contributing to several high-profile feature films. In 2013, he joined ILM as an animator. He quickly rose through the ranks, thanks to his work on acclaimed projects such as The Revenant—an Academy Award-nominated film—and numerous entries in the Marvel Cinematic Universe, including Avengers: Age of Ultron, Captain America: Civil War, and Thor: Ragnarök.

Mcnair was promoted to animation supervisor after being recognised for his expertise and leadership in animation. He continues to push creative and technical boundaries, most recently on Jurassic World: Fallen Kingdom.
