MatPat (Matthew Patrick) has a small cameo in the 2023 Five Nights at Freddy’s movie, but he does not play a major character — he appears as a waiter at a diner called Sparky’s.

His Role in the Movie

In the film, MatPat plays a waiter who serves Jane (Mike’s aunt) and her group at Sparky’s diner. He’s not a named character; he’s just credited as “Waiter” or “Wess” in some sources. During the scene, he tries to get them to order food, saying things like:

  • “Hey, welcome to Sparky’s. Can I set you folks up with some appetizers?”
  • “Well, that’s no fun. You do realize lunch is the most important meal of the day?”
  • “Some people say that, but you know… that’s just a theory.”

That last line is, of course, a direct nod to his famous catchphrase from Game Theory.

Cameo, Not a Main Role

This is purely a fun, blink‑and‑you‑might‑miss‑it cameo, not a major acting role. He’s not one of the main cast (like Mike, Abby, or the animatronics) — he’s just a background character who gets a couple of lines as a tribute to his huge influence in the FNAF fandom.

What About the FNAF Sequel?

In the upcoming Five Nights at Freddy’s 2 movie (2026), MatPat is doing something much bigger: he’s the voice actor for Toy Bonnie. So while he only played a waiter in the first film, in the sequel he’s actually voicing one of the main animatronics.

TL;DR: In the 2023 FNAF movie, MatPat plays a waiter at Sparky’s diner who says his famous line, “that’s just a theory” — it’s a short cameo, not a major character.
