Other mistake: After Johnny takes Captain Stanley's BP, when Chet tells the guys, "Animal fat is the root of all evil," and also after John jokes, "How to survive on no meals a day," check out Roy's feet because he's wearing shoes (looks like black sneakers) that are below the ankle, with no socks. Then in a few moments they're all dispatched to the 'possible heart attack' and when they're at the scene, while Roy is sitting with the patient, he's wearing socks and his uniform shoes (their tops are above the ankle) as usual.
Other mistake: Roy uses the Biophone when he tells Brackett the vitals of a woman with cardiac symptoms, and then Johnny uses the landline to tell Brackett that there's "Another victim, female, 8 months pregnant, she's gone into labor." Brackett responds, "The mother's probably had an MI... Any cervix dilation on the daughter?" It is impossible for Brackett to have known that the two women are related, let alone that they're mother and daughter.
Other mistake: While Johnny and Roy are with the possible heart attack, they've patched her in for the EKG, and in the base station room Brackett looks at the EKG strip and the unit's monitor, then it cuts to a closeup of the Datascope monitor, even though the Datascope is not actually in the ER's base station room.

Other mistake: At the chemical plant, when Captain Stanley gets to the roof and realizes they have to shut off the main valve, over the HT he says, "Engine 8, HT 51, shut off the power..., Engine 15 supply Truck 8...," but the weird subtitles read, "Engine 80, Team 51, shut off the power..., Engine 15, Supply Truck 80..." Then a bit later Captain Stanley tells Mike over the HT, "Engine 51, HT 51, charge the line," but the subtitles read, "Engine 51, Team 51, start your line." Then as soon as Mike charges the line, Captain Stanley tells Roy and Chet, "Okay, full fog, full fog...," but again the weird subtitles read, "Okay, hold strong, hold strong."

Other mistake: When the patient with the heart wound is brought to the ER, the anesthesiologist brings the cart with a ventilating unit close to patient, then there are two closeups of Bird's Mark 4 unit and the bellows housing showing inflation and deflation, and on the bellows unit it reads "Animal Anesthesia Ventilator" made by Bird. This is also the same closeup we see of the ventilator unit in 4x18, "Prestidigitation," during the surgery on Brackett's father.

Other mistake: When Roy and Johnny are with the victim who has a projectile in his heart from a lawn mower, Brackett asks for an EKG strip and there's a closeup of the Datascope monitor, even though the Datascope is not actually in the ER's base station room (it's also still in the squad at this point). Also interesting to note, when Brackett walks out of the base station and tells Early about the heart wound, Early turns the medical chart he's holding at an angle, looks down at it and it appears that he's reading his line from the chart. Then when the ambulance arrives at the scene, the stethoscope is around Johnny's neck, then it's back around Roy's neck as Johnny's lifting the patient, then it's gone from Roy's neck, and then Johnny puts it back around Roy's neck.

Other mistake: When Johnny and Roy are in the kitchen talking about pooling money for Davey's Dogs, there are three small containers of milk on the table which have tape covering the brand names.
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.
Answer: I believe you are speaking of the old man, Mr. Wilson. He's played by J. Pat O'Malley.

Correct, it was J. Pat O'Malley...he also played the grandfather with his grandson when their rocket exploded, and also played "Old Bill" in the episode with Ann Prentiss, where Gage saves the little girl from the burning tree house, and her mother falls in love with him.
