Hounsou does have a role in Aquaman, but it's voice-only. So I'm going to go with your suggestion and switch the example to Shazam! There was actually a third option as well (Constantine), but Shazam! is a more well-known property.
Gotta refer back to the note at the top - this isn't a comprehensive list. And the hints aren't meant to include every Marvel/DC film the actor has been in, just one from each side to give you a shot at guessing the right person.
I eventually gave up on keeping my own similar quiz, on actors who've played multiple comic book characters, comprehensive. With the proliferation of comic book movies and TV shows it was becoming increasingly impossible and ridiculous trying to do so.
If you're planning to add new actors, there is also Joe Manganiello who played Flash Thompson in Spider-man and Deathstroke in the post-credit scene of Justice League
See Kal's note above. It'd be a never-ending battle to keep a comprehensive list up and running. Consider this quiz a snapshot in time from when I first made it.
And please add Taika Waititi and Clancy Brown who were both in Green Lantern and Thor Ragnarok.
also Michael Clarke Duncan was in Daredevil and Green Lantern.
and Fishburne was in Fantastic Four Rise of the Silver surfer. and Brolin was in Deadpool 2.
and please add type-ins for Michelle Pfeiffer.
and Favreau was in Daredevil as well.
and Simmons was in Far From Home as a different version of a character.
