20 Movie Reveals Nobody Noticed

20. Boo's Name Is Mary - Monsters Inc.

In Pixar's stone cold classic Monsters, Inc., the pint-sized human protagonist Boo (Mary Bibbs) is never actually referred to by her real name, only the nickname bestowed upon her by her newfound pal Sulley (John Goodman). 

And honestly that's just fine, but the curiosity about her actual given name endures regardless.

Yet for those paying ultra-close attention to the adorable scene where Boo goes to sleep in Sulley's bed, you might notice that the various drawings she's scrawled are all signed with one single name - "Mary."

And so, it's reasonable to assume that this is her name, and that it was hiding right in front of our faces the entire time. 

But if you somehow still weren't convinced, the official novelisation of Monsters, Inc. indeed confirms Boo to be named Mary.

The name was seemingly lifted directly from Boo's voice actress Mary Gibbs, who is herself the daughter of one of the movie's story artists, Rob Gibbs, who sadly passed away in 2020.
