Annette Bening tried not to give away too much about her “Captain Marvel” role during an appearance on Thursday’s “The Late Show with Stephen Colbert”.

Bening’s part in the eagerly anticipated flick has been kept under wraps but she’s finally confirmed that she’ll be playing the Supreme Intelligence, which was a part created by Stan Lee and Jack Kirby in the 1960s.

The actress said the character was “a God-like entity, the leader of the Kree people, the Artificial Intelligence that consists of the greatest intellects of the Kree people for the last million years.”

Bening said her kids had to explain to her elements of the Marvel Cinematic Universe (MCU).

“When I read the script, I did find it slightly confusing. I took into my confidence two of my kids who I told the story to and asked them to please explain to me what the hell was going on, which they then did.

“My children were actually able to divulge everything to me.”
