Other mistake: While Roy is showing Brice the squad, after Brice annoyingly locks Squad 51's side bay door, he asks, "How about the OB box?" but the subtitles read, "How about the OV box?" Then a minute later Brice says, "Let's look at the OB box," and again the subtitles read "OV box." The OB box is obstetrics supplies, and OV box doesn't exist. Subtitles from Universal Studios 2010 DVD.
Other mistake: After Johnny is hit by the car Roy kneels down beside him and shouts, "Trauma box!" but the subtitles read, "Code box!" There is no code box. Subtitles from Universal Studios 2010 DVD.
Other mistake: When the ambulance arrives and they're loading Johnny onto the ambulance, Captain Stanley says, "Okay, Chet, take the squad..." but the subtitles get both characters wrong, it reads that a "Paramedic" says, "Okay, Chip, take the squad..." There is no Chip. Subtitles from Universal Studios 2010 DVD.
Other mistake: When Early and Morton are examining Johnny, Early points out Johnny's torso as he says, "Mike, you see this bruise?" but the subtitles read, "Frank, you see this bruise?" A couple of minutes later the subtitles get Mike's name right. Subtitles from Universal Studios 2010 DVD.
Other mistake: When Early and Morton are examining Johnny, Early tells the nurse, "Type and cross" (the blood vials she's holding), but the weird subtitles read, "Cut and cross." Subtitles from Universal Studios 2010 DVD.
