It's still a long way to go before "Avengers: Infinity War" trailer is released, but at least director Joe and Anthony Russo have offered us a look at another kind of trailer. As the movie began filming in Atlanta on January 23, the Russo Brothers took to their Twitter to share the first on-set photo, which features a large numbers of trailers.

While the trailers may not reveal much about the movie, they speak volume about bulgy cast members they will probably accommodate. Robert Downey Jr., Chris Evans, Tom Holland, Chris Hemsworth, Mark Ruffalo, Jeremy Renner, Elizabeth Olsen and Paul Bettany are included in returning cast members. They will be joined by "Guardians of the Galaxy" stars Chris Pratt, Zoe Saldana, Karen Gillan and Dave Bautista. "Game of Thrones" star Peter Dinklage is also starring and is speculated to play MODOK, while Benedict Cumberbatch will reprise his role as Doctor Strange.

In a recent interview, Renner and Olsen confirmed they would return in the movie, but admitted that they hadn't read the script yet. Bautista later tweeted that he would soon start filming.

Plot details are still kept under wraps, but it may focus on the alliance between the Avengers and the Guardians of the Galaxy members to fight against villain Thanos, who may collect Infinity Stones to achieve godlike powers.

"Infinity War" and its untitled sequel are planned to be filmed back-to-back, with Atlanta and Scotland as their settings. The Russo Brothers previously also helmed "Captain America: The Winter Soldier" and "Captain America: Civil War".

"Avengers: Infinity War" is scheduled to arrive in U.S. theaters on May 4, 2018.
