"Black Adam" box office failure has Dwayne Johnson discussing "guts to fail."
Johnson advises "guts" is more potent than the "desire to succeed."
Warner Bros execs reportedly annoyed by Johnson's "Black Adam" demands.
Johnson, Garcia, and Flynn had planned to combine "Black Adam" and Cavill's Superman.
De Luca and Abdy approved Cavill's cameo, but Johnson's approach "didn't sit well."
Johnson also wanted credit, and the Teremana brand featured at the "Black Adam" premiere.
"Black Adam" budgeted $195 million, only making $391 million worldwide.
COVID-19 caused the "Black Adam" release to move to December 2021, only making $48 million on the opening weekend.
"Black Adam," set for December 2022 release, promised to be "bigger, badder, and louder" but failed at the box office.
