Mary Gibbs, the voice behind Boo in Pixar’s Monsters, Inc., has turned 30. The milestone came just weeks after she shared a throwback photo on Instagram.
What Happened
Gibbs posted a side-by-side image on her Instagram account. It compared a 2022 photo of her at a fan convention with a 2001 photo of her standing beside a Sully mascot from the film’s premiere.
The post included the caption: “If you don’t feel old yet, the voice of Boo just turned 30.”
Key Facts
- She voiced Boo in Monsters, Inc. (2001), alongside Billy Crystal’s Mike Wazowski and John Goodman’s Sully.
- Gibbs also voiced young Riley in Pixar’s 2015 film Inside Out.
Background
Gibbs originally joined the project through her father, Rob Gibbs, who worked as a storyboard artist on the film. She was brought in to help with animation.
During filming, she recalled a vivid memory of playing a magnetic fish game in the studio. She said, “I remember there was this magnetic fish game where the fish are opening their mouths.”
She noted that voice actors recorded separately in different time slots. The first time she met the full cast was at the premiere, where she said she felt scared. Billy Crystal recognized her fear and comforted her by picking her up and walking her down the red carpet.
Why It Matters
Gibbs has expressed deep gratitude for the impact of Monsters, Inc. on her life. She said, “Growing up being a part of that movie, it’s been really awesome.”
She emphasized that the film has shaped her identity. When people learn she’s the voice of Boo, she said it often surprises them. Her favorite part of the work is meeting fans at comic cons.
What to Watch Next
Gibbs continues to engage with fans through public appearances. She recently shared her experience at a horror con in Wales, saying, “So grateful I get to travel the world and meet Monsters Inc fans all over the world!”
Her reflections on the film and her career show a deep connection to the legacy of the movie.
