Hunger is known for its unbroken 17 minute 10 second continuous shot, in which Catholic priest Father Dominic Moran tries to talk Bobby Sands out of the Hunger Strike he and his fellow 75 IRA members plan to start. The camera remains in the same position throughout the scene. To prepare, Liam Cunningham moved into Michael Fassbender's apartment, and they rehearsed the scene 12-15 times per day. On the first day of filming, the actors got it perfect after 4 takes.
The medical attendant with a mustache who takes care of Bobby Sands in the hospital has 'UDA' tattooed on his left hand. UDA stands for Ulster Defence Association, a loyalist paramilitary organization.
Bobby Sands first appears on screen 26 minutes into the film.
