The Tycoons - S5-E23
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.

Continuity mistake: When the patient with the heart wound is brought to the ER, he's wheeled into treatment 2, which has a window on its door, and is on the side of the hallway with the yellow line closest to it. Later we see treatment 1 twice, when Vince brings in the burglary suspect with a bullet in his leg, and also when John and Roy rush the baby to the ER. They used the same room as treatment 1 and treatment 2, but there are just two treatment rooms on that side of the hallway and only one of them has a window on its door - the one that's opposite the nurses' station, treatment 1.

Continuity mistake: At the nurses' station, after Roy tells Brice that Brightweiser will be okay the two of them walk to receiving carrying their gear, with Roy holding the Biophone and defibrillator, but as they head through the doors both the Biophone and defibrillator have each turned around in Roy's hands, and now face the opposite way.
Continuity mistake: After Roy shows Brice the drug box, Roy places it back into the squad's side bay in the closeup, but in the wide shot Roy's still holding the drug box while Brice acts like his annoying self.
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.
Continuity mistake: When Johnny is being examined by Dr. Early and Dr. Morton, Roy is in the treatment room with them, and he's not wearing a watch, but when Roy steps into the hallway and speaks to Chet he's suddenly wearing a watch.
Answer: I believe you are speaking of the old man, Mr. Wilson. He's played by J. Pat O'Malley.
Bishop73
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.
