After last night’s explosive season premiere of Supergirl, events will continue to accelerate in the coming weeks. Not only do we now have Tyler Hoechlin in the recurring role of Superman/Clark Kent, but soon another superhero will join the cast. As has been widely reported, former Wonder Woman star Lynda Carter will be joining Supergirl for a supporting role. It’s not just another role, though: Carter will actually be playing the President of the United States of America.

Although her name has not yet been given on the series, the fact that a woman is in the White House has been mentioned several times. In Supergirl episode 2×03, ‘Welcome to Earth,’ we’ll finally meet President Olivia Marsdin.

Here’s the official synopsis from The CW:

LYNDA CARTER (“WONDER WOMAN”) LANDS IN NATIONAL CITY AS PRESIDENT OLIVIA MARSDIN — An attack is made on the President (guest star Lynda Carter) as hot-button, alien vs. human rights issues heat up in National City. Supergirl (Melissa Benoist) and the DEO are assigned to protect the President and bring in the responsible party. Alex (Chyler Leigh) teams up with Detective Maggie Sawyer (Floriana Lima) to investigate the case while Kara searches for a recently escaped Mon-El (Chris Wood), who she fears may be the alien behind the assault.

Tank Girl director Rachel Talalay directed the episode. ‘Welcome to Earth’ was written by Jessica Queller and Derek Simon.

Beyond the arrival of Lynda Carter’s president, the presence of Detective Maggie Sawyer and an escaped Mon-El should lead to an action-packed hour of television.
