With the release of Avengers: Doomsday’s fourth teaser trailer now online, Marvel has begun a live countdown clock to the movie’s release on YouTube that’s set to run for more than 11 months.

Avengers: Doomsday will arrive in theaters on December 18, and you can now watch the months, days, hours, minutes and seconds tick down alongside other fans. Will anything else happen on the stream? You’ll just have to tune in and find out — and more than 5,000 fans are currently watching at the time of writing.

The launch of today’s countdown clock does seem to suggest that Marvel is done releasing its weekly Avengers: Doomsday trailers, which have arrived in theaters (and leaked online) before their official release via Marvel’s YouTube channel.

Those four trailers — initially attached to Avatar: Fire and Ash — have given fans a first look at the movie’s big players in action, though revealed relatively little about the overall plot. And, notably, Doctor Doom himself, played by Robert Downey Jr., has remained under wraps.

Only one additional cast member was confirmed throughout the four trailers: Chris Evans, whose return as Steve Rogers prompted some controversy from fans who believe Marvel has run out of fresh ideas. (It’s fair to assume Hayley Atwell will return as his beau Peggy Carter, too.)

Subsequent weeks saw a glimpse at the previously-confirmed Thor (Chris Hemsworth), then a peek at some of the returning X-Men, including Magneto (Ian McKellen), Charles Xavier (Patrick Stewart) and Cyclops (James Marsden), before today’s trailer which features the Wakandans and Fantastic Four’s The Thing.

Fans had hoped for a fifth trailer to arrive in theaters today, but as of yet there’s no sign, and the countdown clock may signify a wait for more (until the Super Bowl on February 8, perhaps).

Of course, this isn’t the first lengthy livestream from Marvel to advertise the impending arrive of Avengers: Doomsday. Last year, the movie’s gargantuan cast list was revealed via the now-infamous ‘chair stream’ which revealed all of Doomsday’s main players via their names written on the back of chairs, in a long line within a cavernous aircraft hanger. At the end, after hours of wait, sat Robert Downey Jr. himself. Could he pop up again via the countdown clock?

At the time of writing, 11 months, four days and a little over 14 hours remain until Avengers: Doomsday’s launch. Excited yet?
