Update #2: James Gunn deleted the above tweet fueling further speculation the Twitter account is in some way legit.
Images surfaced on the "Russo Bros" Twitter account (unknown if official) possibly teasing a red and black Spider-Man costume.
In addition, it appears as if the "Sokovia Accord" is the movie version of the Civil War superhero registration act, as Sokovia was the city destroyed in Avengers 2.
Some of the other images appear to tease Peter Parker's high school, the Ten Rings and possibly Spider-Man's camera.
Joe Quesda, Marvel's CCO, recently stated the new Spider-Man costume is awesome and that it will blow people away.
"Captain America: Civil War" has a May 6, 2016 release date directed by Anthony and Joe Russo starring Chris Evans, Robert Downey Jr., Scarlett Johansson, Jeremy Renner, Elizabeth Olsen, Sebastian Stan, Anthony Mackie, Frank Grillo, Paul Bettany, Don Cheadle, Emily VanCamp, William Hurt, Martin Freeman and Chadwick Boseman as Black Panther.
Captain America: Civil War picks up where Avengers: Age of Ultron left off, as Steve Rogers leads the new team of Avengers in their continued efforts to safeguard humanity. After another international incident involving the Avengers results in collateral damage, political pressure mounts to install a system of accountability and a governing body to determine when to enlist the services of the team. The new status quo fractures the Avengers while they try to protect the world from a new and nefarious villain.
