The voice of Venom in the Venom movies is primarily performed by Tom Hardy, who also plays Eddie Brock, the character bonded with the Venom symbiote. Hardy pulls double duty by voicing both Eddie and Venom, essentially talking to himself in many scenes. He created Venom's voice by blending influences from artists like Redman, Busta Rhymes, James Brown, and Richard Burton, aiming for a bombastic, playful, dark, witty, and powerful sound. Hardy’s voice was further layered with effects in post-production to achieve Venom’s distinctive low, resonant, and gargling tone

. In the first Venom film, Hardy's voice was combined with that of veteran voice actor Brad Venable, who contributed to Venom’s vocal layers but was uncredited. Venable passed away in 2021 and did not participate in subsequent films. For Venom: Let There Be Carnage , Hardy deliberately changed Venom’s voice to reflect the character’s development, making it less menacing and more upbeat to match the symbiote’s evolving relationship with Eddie Brock

. In summary, Tom Hardy is the main voice of Venom, supported by Brad Venable in the first film, with Hardy’s vocal performance being central to the character’s distinctive voice throughout the series
