Marvel Studios is kicking off Phase Four with high-wattage star power.

Angelina Jolie surprised fans at San Diego Comic-Con Saturday evening along with the cast of the upcoming film "The Eternals." Marvel Studios President Kevin Feige says it will hit theaters Nov. 6, 2020.

Jolie was joined on stage by fellow cast members Richard Madden, Kumail Nanjiani, Bryan Tyree Henry and Salma Hayek, as well as director Chloe Zhao.

Jolie says she's already in training and is going to work 10 times harder than she has on any action film before.

Phase Three of the Marvel Cinematic Universe ended this summer with "Spider-Man: Far From Home" and "Avengers: Endgame."

Feige also says "Endgame" will surpass "Avatar" as the highest-grossing film ever in a few days.
