'Breaking Bad''s Aaron Paul is the latest to join 'A Long Way Down,' the adaptation of the Nick Hornby novel in which four people decide to kill themselves. It's a real heart-warmer, you guys.

Aaron Paul flew under the radar for years before hitting the big time on AMC's 'Breaking Bad,' playing Jesse Pinkman, the bad boy with a good heart. According to Deadline, his star will continue to rise as he's just joined the upcoming film 'A Long Way Down,' from director Paschal Chaumeil and writer Jack Thorne ('Skins'), replacing Emile Hirsch.

The film is based on the Nick Hornby novel of the same name in which four people meet on New Year's Eve at the top of a building as they all plan to kill themselves. Instead, the group form something of a surrogate family and help each other through their difficult times. Paul will play a pizza delivery man alongside previously announced stars Toni Collette, Pierce Brosnan and Imogen Poots, who respectively star as a mother of a disabled boy, a troubled television talk show host, and a teenage girl.

Hornby is famous for his novels 'About a Boy' and 'High Fidelity,' which were both previously adapted into critically acclaimed big screen versions.
