It’s unknown if Doctor Strange will be appearing in Ant-Man and the Wasp, but set images did reveal Paul Rudd for Avengers: Infinity War.
I believe both movies are filming at the same location in Atlanta, Georgia.
The Avengers: Infinity War hits May 4, 2018.
Ant-Man and the Wasp opens July 6, 2018 directed by Peyton Reed starring Paul Rudd as Scott Lang/Ant-Man, Evangeline Lilly as Hope Van Dyne/Wasp, Michael Douglas as Hank Pym, Michelle Pfeiffer as Janet Van Dyne, Michael Peña as Luis, Laurence Fishburne as Doctor Bill Foster, Hannah John-Kamen as Ghost, Randall Park as Sgent Jimmy Woo, Judy Greer as Maggie Lange and Walter Goggins as Sonny Burch.
From the Marvel Cinematic Universe comes a new chapter featuring heroes with the astonishing ability to shrink: Ant-Man and The Wasp. In the aftermath of Captain America: Civil War, Scott Lang (Rudd) grapples with the consequences of his choices as both a Super Hero and a father. As he struggles to rebalance his home life with his responsibilities as Ant-Man, he’s confronted by Hope van Dyne (Lilly) and Dr. Hank Pym (Douglas) with an urgent new mission. Scott must once again put on the suit and learn to fight alongside The Wasp as the team works together to uncover secrets from their past.
