The early 2000s internet was a stranger, more innocent place. Movie news didn’t arrive in polished studio livestreams or carefully coordinated social media drops. It came through grainy message boards, rumor-heavy fan sites, and low-resolution teaser trailers rolled out before other movies in actual theaters — often with no branding, no stars, and sometimes no clear indication of what the movie even was.
And for one brief, bizarre moment in late 2001, an in-theater teaser had a whole lot of people convinced they were about to witness the return of Batman.
It turned out to be a CGI Great Dane.
The Setup
Picture this: you’re in a multiplex in November 2001. You’ve shown up early for Harry Potter and the Sorcerer’s Stone. The lights dim. The trailers roll. And then one rolls that opens on a dark, gothic sky. Lightning. A mansion. Shadows. Bats, because of course there are bats.
A silhouette of a caped figure stands framed in a window. Pointy ears. Cloak billowing. The score swells toward something heroic. The voiceover booms:
“And now… in the summer of 2002… he will be called upon yet again to save the world.”
For a split second, every Batman-starved adult in that theater had the same exact thought: wait, are we getting another Batman?
Then the figure turns around.
It’s Scooby-Doo. He looks at the camera. “Who, me? Ruh-uh!”
Record scratch. The lights come up. Everyone in the theater either laughs or dies of secondhand embarrassment, or both.
Why It Actually Worked
You have to remember where Batman was in 2001. The franchise had been dead for four years, ever since Batman & Robin napalmed it on arrival in 1997. Batman Begins wouldn’t exist until 2005. The Caped Crusader had been in development hell for the entire back half of the ’90s — everyone knew a new Batman was coming, eventually, someday. No one knew when. The actual answer turned out to be: not yet, but here’s a computer-generated dog voiced by Neil Fanning instead.
At the same time, live-action adaptations of nostalgic cartoons were suddenly having a moment. The Flintstones had been a hit in 1994. How the Grinch Stole Christmas made $345 million in 2000. A live-action Scooby-Doo directed by Raja Gosnell, starring Freddie Prinze Jr., Sarah Michelle Gellar, Linda Cardellini, and Matthew Lillard, wasn’t impossible — it was just, in November 2001, not on most people’s radar yet.
That disconnect is the engine of the whole gag. Warner Bros. knew it owned Batman. Warner Bros. knew it owned Scooby-Doo. And Warner Bros. correctly guessed that if it leaned hard enough into its own house-of-horrors aesthetic, a decent chunk of the audience would spend 40 seconds assuming it was being handed one before getting handed the other.
A Lost Art
Modern trailers don’t do this anymore.
Modern trailers are transparency machines. The studio logo hits in the first three seconds. The A-list cast is front-loaded. The movie’s title is plastered across every frame that might plausibly end up as a TikTok thumbnail. There’s no room for surprise, because surprise gets you skipped.
Older teaser campaigns were willing to misdirect. They assumed the audience was a partner in the joke, not an engagement metric. They trusted that a 45-second bit with a rug-pull at the end would be more memorable than a straightforward “here are all the stars and the plot and the release date” sizzle reel.
And honestly? Two decades later, nobody remembers the regular Scooby-Doo trailer. Everybody who saw the Batman one in theaters remembers the Batman one in theaters.
The Payoff
When Scooby-Doo finally opened on June 14, 2002, it grossed more than $275 million worldwide on a reported $84 million budget, spawned a 2004 sequel (Scooby-Doo 2: Monsters Unleashed), and launched a weird, enduring second life as a legitimately beloved cult movie — the kind of film where grown adults still argue about whether the James Gunn-penned script was funnier than the movie we actually got.
But the teaser? The teaser is the real piece of pop culture history.
Because for one glorious, darkened moment, thousands of moviegoers in the fall of 2001 genuinely thought Gotham’s protector was finally coming back to the big screen.
Instead, it was a dog asking for snacks.
