As Edgar Wright has proven time and time again in his work (both in film and television), he is a master of foreshadowing, and here he’s created a stellar time-release joke for Baby Driver. As the movie plays out, you watch as the heist teams Doc sets up change rosters — a nod to Quentin Tarantino’s Reservoir Dogs — and you don’t really think much about Griff after he leaves the screen since the idea is to never organize the exact same group of thieves twice.
It’s not really until you’re thinking about the movie later on and wondering about what happened to Griff that you get the punchline: Griff’s last line is, “If you don’t see me again, I’m dead.”
