Gregory S. Butler (born August 18, 1971, Suffield, Connecticut) is an Academy Award-winning American visual effects supervisor.
Despite his initial plans to study history, a work-study job with the audiovisual equipment in the library made him interested in film production.
Following a job at Rocket Science Games until the company's bankruptcy in 1996, Butler went to Tippett Studio and did effects work in Starship Troopers and My Favorite Martian, rising up to a technical director job, and Cinesite for Practical Magic.
While reluctant at the requirement of moving to New Zealand, Butler was convinced by his writer-actor brother to jump at the opportunity of working for Weta Digital in The Lord of the Rings.
