@wired: “Mountainhead,” which will start streaming on HBO May 31, stars Steve Carell as venture capitalist Randall; Jason Schwartzman as Hugo Van Yalk, whose nickname “Souper” is a reference to a soup kitchen—and his lower net worth; Cory Michael Smith as Venis, a Zuck-Elon figure; and Ramy Youssef as Jeff, who plans on profiting big from releasing AI that can counter the chaos his pal Venis is wreaking on the world.
