-Jack "Fight Club"-

Occupation: Claims and Damage Adjustment Consultant at a major automotive company. His job involves investigating car accidents to determine insurance claims.

Lifestyle before the club: An office worker obsessed with buying designer furniture and items from the IKEA catalog. He suffers from chronic insomnia due to an existential crisis and a sense of emptiness in his life.

• Psychological condition: Experiencing severe stress, alienation and dissociative identity disorder (split personality).

• Conformism and depression: During the day, this is a quiet, insecure and obedient cog in the consumer society system.
• Emotional Search: His inability to sleep and feel real life pushes him to attend psychological support groups for the terminally ill, where he fakes other people's diagnoses in order to "cry" and experience false relief.
• Duality: His alter ego is the charismatic, confident, cynical and aggressive anarchist Tyler Durden, who takes control of the Narrator's body at night.

• Physique: Average, office-type, slightly emaciated or worn out by chronic insomnia. For the role, actor Edward Norton lost approximately 10 kg to emphasize the lifelessness and fragility of his character in contrast to the athletic Tyler Durden.
• Face and look: Pale skin, tired appearance, dark circles and bags under the eyes from constant lack of sleep. The facial expression is often detached, tense, or the empty look of an office worker.
• Hairstyle and style: Short dark hair, neat or slightly careless cut.
• Clothing: Casual office suits, boring shirts and ties at the beginning of the film (symbolic of the drab office life), which change to worn-out clothes as he gets into the Fight Club atmosphere.
• Physical changes throughout the story: Due to his involvement in fights, his face and body are regularly covered with bruises, cuts, swelling, and scars.
