Today is a special day for The Sandman universe. For one, it's the 35th anniversary of the very first issue of The Sandman. It also happens to be the day that we learn that the second season of Netflix's The Sandman is back in production out in London.

To commemorate the occasion, Netflix released a great behind-the-scenes photo of the production (which you can see above) and Neil Gaiman released a letter to the fans tracing the path of The Sandman from its beginnings more than three decades ago to today. "This week we officially restart production on the next sequence of stories of The Sandman for Netflix," Gaiman writes. "Genius show runner Allan Heinberg and the countless people in front of and behind the camera are building something endlessly special, and bringing these stories to life in a way that would once have been unimaginable."

As for what fans can expect from a second season, Gaiman writes, "A journey is beginning that will take us from Destiny’s garden to Hell, from the Heart of the Dreaming to Ancient Greece and revolutionary France, and from there to places even I cannot quite imagine on the screen. I will be patient. Good things are coming."

We'll certainly have to use our own patience too. Though it's a great sign that the show is back in production, it will likely be a while before we see it on the home page of our Netflix accounts. But hey, all good things are worth the wait.
