If negotiations are successful then she will join Samuel L. Jackson, Ben Mendelsohn, and Kingsley Ben-Adir in the series.
Jackson returns as Nick Fury in the series, while Mendelsohn will play the Skrull Talos. They will reunite for the first time since Captain Marvel to uncover that a faction of shape shifting Skrulls have been infiltrating Earth for decades.
Colman’s role is being kept under wraps, while Ben-Adir will play a main villain. Hints at the Secret Invasion have appeared in everything from Spider-Man: Far From Home to WandaVision.
Kyle Bradstreet is attached to write and executive produce.
Colman would be a big deal for the MCU to attract, holding an Academy Award and Golden Globe for The Favourite being nominated for them both again for The Father.
She also won the Golden Globe in 2020 for her role as Queen Elizabeth II in The Crown and another in 2016 for The Night Manager. This was on top of Emmy nominations for Fleabag and The Night Manager.
Basically, critically acclaimed hot property right now.
