The actress, who will be next seen in the sequel of Marvel's 2015 'Ant Man' titled ' Ant Man and the Wasp,' shared the first photo of herself wearing her wasp costume.
She shared the photo on her official Twitter handle and captioned the snap as, "I am honoured to be on set today playing #TheWasp on what would be Jack Kirby's 100th birthday."
Kirby co-created Janet van Dyne (the original Wasp) along with Stan Lee back in 1963. Lilly plays Hope, the daughter of Janet van Dyne and Hank Pym (the original Ant-Man).
Lilly's Wasp suit was first glimpsed at the end of 2015's Ant-Man, and Marvel revealed at San Diego Comic-Con that the film would also include original Wasp Janet van Dyne, to be played by Michelle Pfeiffer. Paul Rudd will reprise the role of Ant-Man.
Peyton Reed is once again in the director's chair, with Michael Douglas returning as Hank Pym.
Laurence Fishburne is joining the series as Bill Foster, who, in the comics, worked as a scientist alongside Hank and later became a size-changing superhero in his own right, initially as Black Goliath and then as Giant-Man.
'Ant-Man and the Wasp' is set to hit the screens on July 6, 2018.
