Frances Bay — Grandma Gilmore — Frances Bay — Grandma Gilmore

Bay played Happy's grandmother, whose house provides the original film's concrete stakes. Her long career included roles in Blue Velvet, Twins, and Seinfeld, often turning a small part into a memorable presence.

Bay died in 2011. Happy Gilmore 2 acknowledges Grandma within the story, but no new performance should be implied by that tribute.
