Watch Doc Brown’s Back to the Future Day Message to the World

It’s Oct. 21, 2015, so Doc Brown naturally has a message for you.

Social media has been abuzz for hours already, with Back to the Future fans celebrating in a variety of ways — from watching out for Michael J. Fox’s character Marty McFly (who traveled forward to exactly this date in the iconic movie trilogy’s second installment in 1989), to continuing to pray for a mass-produced version of that hoverboard, and wondering…what now?

But Brown, the eccentric genius and time machine inventor played by Christopher Lloyd, has a reassuring message for those who worry that self-lacing shoes aren’t really a thing yet.

“Yes, it is different than we all thought,” he says in a video uploaded to the movie series’ official Facebook page. “But don’t worry, it just means your future hasn’t been written yet. No one’s has.”

Here’s the whole video — shot inside the iconic DeLorean time machine, of course.
