Atlanta has been home to several Marvel Studios films over the years, including "Ant-Man," "Captain America: Civil War," "Guardians of the Galaxy Vol. 2" and, most recently, "Spider-Man: Homecoming". A new photo tweeted out by Robert Downey Jr. with a couple of the latter's stars suggests there could be another major project coming to the major Southern filming location -- from none other than Marvel alum and "Iron Man" director Jon Favreau.RELATED: Spider-Man Homecoming Adds Robert Downey Jr.Around 6AM central, Downey Jr tweeted out the following image, announcing a collaboration between Jon Favreau -- who'll be reprising his role as Happy Hogan in "Spider-Man: Homecoming" -- and celebrity chef Roy Choi. Curiously, the pic also features Spider-Man actor Tom Holland, directors Anthony and Joe Russo ("Captain America: Civil War") and Marvel Studios President Kevin Feige, in addition to Choi and Favreau. Could the get together be an unintentional Marvel Team-up...or something bigger?

Of course, Favreau and Downey Jr. collaborated on the first two Iron Man films, in addition to the 2014 film "Chef", which was inspired by Choi. Choi, among his many other accomplishments, is the creator of the Kogi food truck company, specializing in BBQ and tacos. He also wrote "L.A. Son: My Life, My City, My Food," which details his journey from fine dining chef to food truck owner.

Downey explicitly says this new project is a collaboration between Jon and Roy --without mention of his own name -- and, via The Wrap, Roy shared the same picture on his personal Instagram, asking fans to stay tuned for more information. Otherwise, no further details have been revealed about the upcoming Favreau/Choi project.
