Tom Hardy has tried to explain how the alien sounding voice of Venom is created.
Venom is an alien symbiote that has bonded with Eddie Brock, an investigative journalist.
According to Screenrant, the character first appeared in The Amazing Spider-Man #300 in 1988.
Since then, Venom has become the archnemesis of Spider-Man.
When Venom bonds with Brock, the two become something that is more alien than human.
Hardy, who portrays both Venom and Brock, explained to EW how his sound team created the unique voice.
?I?d have to lay down the vocal for Venom in the morning and then play Eddie opposite in my earpiece, and whoever was working in the scene with me, had to hear Venom at the same time but then ignore that they?d heard Venom.
And whenever I gave my cue line as Eddie Brock [...] Patrick [Anderson] would be under the stage queuing Venom accurately so I could cut across him and talk and argue with myself, and stuff like that.
