We know a lot about Castle's Detective Kate Beckett — like her love of nerdy sci-fi shows and her secret tattoo, just to name a couple — but some tidbits escape even the most diehard fans. Take for example, Beckett's middle name.

In a recent panel discussion at University of Southern California with show creator Andrew Marlowe and actress Stana Katic, the detective's unconventional middle moniker came up in conversation. Marlowe not only revealed the name, but he also explained the inspiration behind it.

Kate Beckett’s middle name is Houghton, inspired by legendary actress Katharine Hepburn, who was known for her independent spirit and feisty personality.

"I thought that was cool," Stana said smiling.
