Five Nights at Freddy's (2023)

Steve Raglan: Just keep your eyes on the monitor.

Trivia: Minor Spoilers: There's a mid-credits scene showing the cab-driver being frightened by the Balloon Boy figure appearing in his car. And in the final moments of the credits, the music volume lowers, and we hear a robotic voice spell out the words "Come find me."
