Take a first look at ITV's brand new action-adventure drama Jekyll and Hyde, starring Tom Bateman.
Jekyll is a young, sensitive and naive man of intellect and morality, a well meaning if slightly repressed character who slips between his two personas unwillingly.
Hyde is a totally different person; a superhero with super powers, great strength, speed and invulnerability. He is confident, risk-taking and lives life on the edge. His self-destructive nature gets him into trouble, and yet he is an incredibly powerful force. He is a man of action who gets things done despite the consequences!
Throughout the series we will witness Jekyll wrestling with the dark, brooding personality of Hyde as he struggles to come to terms with his superhero alter ego.
