>>211902557 (OP)It’s a combination of factors. Basically WB didn’t want Cavill who was associated with Snydershit but they were bound to his contract (one more appearance) which Cavill was holding out for a fully fledged movie, so WB avoided the character like the plague. Cavill fulfilled his contract by appearing in Black Adam which the rock and his ex-wife(Cavill’s manager) convinced him that was the future and everything would be alright. Abdy and De Luca assured him too. A month later Gunn fires Cavill and here we are now.
Allegedly Tobey Emmerich really really hated Cavill and wanted Gunn to direct Superman back in 2018/2019, outright rejecting Christopher McQuarrie’s proposal because “if Gunn won’t do it nobody can.”
