Sony Pictures showed a few more scenes of the symbiote itself in action during their Venom presentation at San Diego Comic-Con on Saturday. The footage didn’t feature finished visual effects but it did show off the creature’s size, ferocity, and his interactions with Eddie Brock as well as his dark wit.
The footage began with Eddie meditating while listening to self-help audio, which instructed him that while he couldn’t change what happened in the past, he can be in total control in the present. We then see the effects of the symbiote taking him over, some of which we’ve already seen in the trailers where he complains of feeling sick.
We saw more footage of symbiote tentacles shooting out of Eddie’s body in his apartment as its voice speaks inside Eddie’s head. But our first real good Venom shot was an outdoor scene of the Venom symbiote’s head protruding from Eddie’s body in order to speak to him.
