A Long Way Down (originally titled Up & Down) is a 2014 black comedy film directed by Pascal Chaumeil, loosely based on author Nick Hornby's 2005 novel of the same name. It stars Pierce Brosnan, Toni Collette, Imogen Poots, and Aaron Paul as four strangers who meet on the roof of a London building on New Year's Eve, each with the intent of dying by suicide. Their plans for death in solitude are ruined when they meet as they decide to come down from the roof alive, however temporary that may be. The film received mostly negative reviews, with criticism of the source material and the film's cast.

Martin Sharp is contemplating suicide on New Year's Eve on the roof of the Toppers Building, high above London's streets. He is interrupted by a woman, Maureen, who has the same fate in mind. She shyly offers to wait her turn, until two other strangers, a young woman named Jess and a pizza deliverer called J.J., also turn up.

Martin is recognised by the others, having been a popular television personality before going to prison for a relationship with a girl who turned out to be 15. After talking things over, the four strangers form a pact, vowing to wait at least until Valentine's Day before again attempting suicide.

Maureen has a disabled son she adores, but little life beyond that. Jess is the daughter of a politician and their relationship is strained. J.J. is an American who once played in a band, but while his three new acquaintances are suicidally depressed, he claims that he is terminally ill with cancer.

To profit from misfortune, Martin hatches a scheme that makes them the talk of London, claiming their mass suicide was interrupted by a vision. They end up on his old TV chat show, where Martin's former co-host Penny makes her guests feel humiliated and even more depressed.

The four go on vacation to get away from London's attention. They enjoy each other's company, until it is revealed that J.J.'s claim about cancer was a lie and the intervention of a journalist named Kathy drives them apart. After the vacation, the four resume their lives. When Maureen's son Matty suffers a heart attack, Jess and Martin visit Maureen in the hospital but J.J. cannot be contacted. They realise it is Valentine's Day and that their pact has ended. All four end up back in London on the very same rooftop with the other three coaxing J.J. away from the edge successfully.

On New Year's Eve that year, they video call each other. Martin is looking after his daughter, Maureen is enjoying herself at a New Year's party, and J.J. and Jess are in a happy relationship.

Brosnan has stated that TV presenter Richard Madeley was an inspiration to him in playing the role. While reading the script for the film in the Colombe D'Or restaurant in Saint-Paul-de-Vence, Brosnan stated that he saw Madeley and his wife Judy Finnigan and later said, "I think it's his sheer ebullience and enthusiasm. You have to be almost shamanic to do it, really, and really believe in yourself. And it's a thin line between being affable and being really annoying. So it takes a brave soul, really."^[4]

The film premiered at the 64th Berlin International Film Festival on 10 February 2014.^[5]
