They already had the perfect superman with Cavill, but since warner bro is obviously ran by a bunch of idiots, the only other logical choice is this dude Giacomo Gianniotti - IMDb
https://www.imdb.com/name/nm5521198/ .. Whether he can act or not is another question, and not for me to decide, but if Cavill is indeed off the table he (definitely looks the part) should be next in line for a call...No other big name star fits the role as well as Cavill, ya Mathew "Boner" is alright but he isn't really a big name and is already a bit old for the part-- anything they do from here on out will fill forced so they better take their time with casting and proceed with caution
