In the first trailer for Ant-Man and The Wasp: Quantumania, we see that Scott Lang (Paul Rudd) still can't believe he's a member of the Avengers.
However, when his daughter Cassie (Kathryn Newton) shows him, Hank Pym (Michael Douglas), Hope Van Dyne (Evangeline Lilly) and Janet Van Dyne (Michelle Pfeiffer) an invention that sends a signal down to the Quantum Realm, Janet tells her to turn it off immediately, but it's too late.
Find out what happens (and who turns up!) by watching the action-packed trailer above. ~Alexandra Heilbron
