The first teaser trailer for Anthony and Joe Russo's Avengers: Infinity War won't release until it's ready, says the filmmakers. The highly-anticipated superhero team-up movie is the beginning of the end of the Marvel Cinematic Universe's first saga, culminating 10 years and 22 movies worth of storytelling into an epic showdown between the Earth's mightiest heroes and the Mad Titan Thanos and his loyal Black Order.

Infinity War wrapped production this past summer, and principal photography on the currently untitled Avengers 4 is already underway. And while the first batch of Infinity War footage was screened at D23 Expo 2017 and San Diego Comic-Con 2017 (you can read Screen Rant's footage description HERE), the directing duo was hesitant to reveal when the first teaser trailer would debut for the general public to see. Marvel Studios head honcho Kevin Feige suggested the trailer could release along with Taika Waititi's Thor: Ragnarok, but that didn't happen. It's unclear when the first trailer will drop, but Feige has promised that it will come before the end of the year - and the Russos want people to stop asking them about it.

The Russos have dug an old advertisement Orson Welles used to air in the '70s and '80s for California wine company Paul Masson - which popularized the phrase: "We will sell no wine before its time." - and they're using it to tell fans that the trailer won't release before it's ready. Although it's not what fans wanted to see, the Russos can't be faulted for their clever use of Welles' infamous adverts. Take a look:

The first trailers for Joss Whedon's The Avengers and Avengers: Age of Ultron released in October, and since it's already November, it seems the studio is taking a different approach this time around. It's possible that the trailer could air in the middle of the season 1 finale for ABC's Inhumans next Friday, which would make sense considering the show's declining ratings. Or the trailer could air alongside Agents of S.H.I.E.L.D.'s season 5 premiere in early December. In either case, it's fair to assume that the trailer will be out before Rian Johnson's Star Wars: The Last Jedi hits theaters in mid-December to capitalize on the global phenomenon.

Whenever the trailer does release, it will be different than the one that was shown to audiences at the convention circuit this past summer. Joe Russo previously said that the footage screened at Comic-Con was made specifically for Comic-Con, and the one they'll eventually release for the general public will be geared to a wider audience. And while Marvel Studios co-president Louis D'Esposito recently said that Avengers: Infinity War's trailer is being edited, it's unclear when it will finally release.
