[10][11] Angus MacLane was born on April 13, 1975, in Riverside County, California, but grew up in Portland, Oregon.

He worked as an animator on every Pixar feature film from A Bug's Life (1998) through Toy Story 3 (2010).

He originally wanted BURN-E's story arc part of the actual film, but Stanton ended up wanting him to develop it into a short which eventually became BURN-E, which can now be viewed on the DVD and Blu-ray releases of WALL-E. For a short amount of time, he worked on the animation for Up, and the animation on Toy Story 3.

After BURN-E, MacLane started to move further to directing and writing works in the studio with Toy Story Toons: Small Fry and Pixar's first TV special, Toy Story of Terror!, for which he won an Annie for Outstanding Achievement in Directing in an Animated TV/Broadcast Production.

[7][8] Following the box office failure of Lightyear, MacLane was among 75 Pixar employees laid off by The Walt Disney Company as part of an ongoing company-wide restructuring in May 2023.
