Matt Smith leads this troubled father-son road trip across the Sussex coast in the twisted tale of The Death of Bunny Munro.

Following wife Libby’s suicide, Bunny continues on as if nothing has happened – instead absconding with his nine-year-old son, Junior, when the social services come knocking.

But long-hidden emotions have a way of bubbling to the surface, especially amid grief, and Bunny can’t keep running forever.

While Bunny’s inner circle continues to dwindle due to his behaviour, here are the key people you need to know, and who plays them.

Heavy drinking, party-loving, and sex addicted Bunny thinks he’s cracked life. With wife Libby and a son at home, he spends his days as a door-to-door cosmetics salesman, sleeping with the women he flogs his wares to, and his nights in hotel rooms with sex workers or women he can pick up. But when Libby’s death shakes his resolve and he finds himself the sole carer of Junior, he finds his priorities shifting as he tries to find a new balance to his life.

Junior adores his mum and idolises his dad, putting them both on a pedestal – for better or for worse. Smart beyond his years, the youngster spends his days reading an encyclopaedia and learning new facts about the world. Sensitive and kind, the death of his mother rocks him, and now he needs his dad more than ever. When he’s not around, he still speaks to his mother as he processes his grief over the loss.

Troubled Libby was not in the life she wanted when she died. Falling head over heels for Bunny, she now spends her time looking after their son, Junior, and struggles with her mental health. Once free-loving and happy, she’s now downcast and done with life. But she has a significant impact on those around her – especially Bunny and Junior once she’s gone.

Poodle is Bunny’s foul-mouthed and at times grotesque best mate, who is always up for a party no matter what the occasion (and by party, we mean with drugs and alcohol). Regularly propping up the bar at the local pub, it’s stranger to find Poodle sober than hungover or drunk. While he is not exactly the most tactful around Libby’s death, he does care for Bunny and works alongside him at the cosmetics company.

Geoffrey is Bunny’s manager at his cosmetics company Eternity Enterprises – though a lot of the time ends up acting as Bunny’s receptionist as the salesman is so flaky. Dishing out clients to his team, he has a foul sense of humour and a macho schtick but is also a relatively honest man who would rather be Bunny’s surrogate father figure than his boss.

Kind-hearted but no-nonsense Yvonne is a stripper at Bunny’s local pub. A single mum living in a flat, she works hard with the small amount of money she has to make sure that her son, Christopher, gets everything he needs. She’s raised a sweet kid, with Christopher just as kind and friendly as his mum, and together they show Junior a more ‘normal’ way of life that Bunny doesn’t provide.

The Original Bunny Munro, Senior has a glistening reputation in the eyes of his son, who talks about his escapades as an antique salesman to anyone who will listen – especially Junior, who laps it up. However, now 70 years old, it’s clear his golden days are behind him, and what remains is a bitter old man who will blame anyone for his problems but himself.

Libby’s mother, Doris has zero time for Bunny or Junior following her daughter’s death. Having been aware of Bunny’s cheating and scoundrel-like behaviour for years, she blames Bunny for breaking her daughter down mentally, leaving her a shell of the bubbly person she once was. With Libby gone, she doesn’t even try to hide it: Bunny disgusts her.
