Assassin’s Creed has officially begun its marketing campaign, revealing a new banner for the upcoming live-action film based on the popular video game. In addition to the simple banner image, 20th Century Fox has launched its viral marketing, which includes a new website and an image that leads to a very interesting message…that might reveal when we’ll see the first trailer.

Fox has debuted the official Abstergo website, and while it doesn’t currently offer anything in the way of special content (or any real content at all), the film’s Twitter account offered an image of business cards for company CEO Alan Rikkin:

If you call the number on the cards, you’ll hear this message:

Hello, you’ve reached the voicemail of Alan Rikkin. I’ll be out of the office on business until March 25 with limited availability.

March 25? Hmm. That happens to be the day that Batman v Superman: Dawn of Justice hits theaters, so that could very well be the day we see the first teaser trailer for Assassin’s Creed. Here’s the new banner:

Justin Kurzel is helming the live-action adaptation, re-teaming with his Macbeth stars Michael Fassbender and Marion Cotillard, along with co-stars Michael K. Williams, Ariane Labed, Jeremy Irons and Brendan Gleeson. It should be noted that Irons appears in Batman v Superman as Bruce Wayne’s loyal butler, Alfred, so there’s definitely a connection.

The Assassin’s Creed movie centers on a man named Callum Lynch, who utilizes a new technology to access what’s known as “genetic memories,” allowing him to live as his ancestor, a 15th century assassin named Aguilar. Through these experiences, Lynch discovers a centuries-long war between the assassins and the Knights Templar — a war he’ll continue to fight in present day.

Assassin’s Creed hits theaters on December 21, 2016.
