In the comics, the Life Foundation is responsible for creating the symbiotes Scream, Riot, Agony, Lasher and Phage.
As for the other two actors mentioned in MCU Exchange’s report, Scott Haze and Riz Ahmed, unlike Jenny Slate, they apparently are playing characters who do originate from the comics.
Haze, recently seen in Only the Brave, will portray Roland Treece, while Ahmed of Rogue One and The Night Of fame will portray Carlton Drake.
It remains to be seen what the Life Foundation is plotting in the Venom movie, but if the group is anything like its comic book counterpart, than it’s up to no good.
