Other: The actress who plays Nancy McNally, Anna Deavere Smith, sometimes has her name spelt Anna Deveare Smith in the credits. It's happened in quite a few episodes. Not sure which is the correct way.

Factual error: During the face-off about religion/politics, they get into a shouting match about commandments, both groups being equally convinced that "honour your father and mother" is the 1st or 3rd commandment, respectively. In actual fact it's the 4th or 5th, depending on which version (Catholic or Protestant) of the 10 commandments you go by. See http://www.positiveatheism.org/crt/whichcom.htm.

Factual error: When Leo is reminding the Congressional Aides about their bosses' drug scandals, he states that Vicodin is a Schedule II Controlled Substance. It is actually a Schedule III Controlled Substance. Given his experience in this area he'd know better.

Continuity: When Toby is walking back to his office from the press room with his ex-wife, the ex-wife's tag and chain keeps changing through the entire sequence. Sometimes it's over her jacket and the tag's just hanging or it's under the jacket and the tag is sitting just inside her jacket.

Other: I call this one an "Escher Mistake". As Donna and Josh near the end of their chat about the chair that needs repairs, they pass an office door on their left (Nancy McNally's office) just before going through another doorway. The camera that follows them passes "through" a solid wall and emerges in an office, facing a hall and stairwell as Josh and Donna enter from our left as if this has all been a continuous shot. But the camera-through-the-wall moment is actually a cut so that the actors can be on a totally different part of the set. This would be fine, except the staircase they are about to turn left to and climb only rises up about 3 feet, then the user turns left again and heads to our left - but that sends the user into McNally's office, and does so 3 feet off the floor, yet they are seen entering the press room instead.

Revealing: When the Secret Service drags Hoynes out of the White House lobby, they exit through the main entrance, doors that are shown in episodes before and after as leading directly outside. But instead of seeing a convincing night exterior this time, the flashing cameras reveal nothing but a blue studio backdrop is out there.

Factual error: Sam says the "state-of-the-art" oil tanker he recommends can carry 2.2 million gallons of oil and weighs 308,000 tons. The Exxon Valdez could carry over 60 million gallons (1.48 million barrels) and weighed only 211,500 tons. The writers mistakenly swapped 'gallons' for 'barrels' so that this enormous tanker carries very little oil. It would actually carry 2.2 million "barrels", which equals 92 million gallons.

Other: When Toby tells Sam to "Go back to the office", the subtitles add "Let's", suggesting both are going, but only Sam leaves.

Continuity: When Ainsley Hayes and Lionel Tribbey are talking in her office, the bottled water moves from being to the right of the framed picture on her desk in the shots over her shoulder to being behind the picture in the shots of her desk from the front.

Plot hole: In order to allow time for a lengthy scene conversing while walking, actor John Spencer is sent on a ridiculous course through the West Wing. See the floor plan at http://www.whitehousemuseum.org/west-wing/west-wing-TV.jpg to follow along. He's first spotted leaving Margaret's area (blank space located just up and left of his "Chief of Staff" office on the plan). The handheld camera is in the Roosevelt room at this point. He turns right, traveling between his office and the Roosevelt room, meeting Donna along this hall. They make two slight left turns, then a hard left, entering the Roosevelt room (at the top/right corner's diagonal door). They walk the length of the room, turn left (down) and Leo drops some of the paperwork he carries onto the end of the table. They then exit the room (bottom left door) which is right outside the doorway where Leo started the scene. Leo isn't wandering. He's quite deliberate in his choices, yet if he'd simply walked straight ahead 6 or so steps from where he started, he'd have been where he dropped the papers.

Continuity: As Margaret enters Leo's office, the bottom corner of her ID tag is tucked into the sweater's button area. It remains this way when she stops walking. The camera reverses angle for a moment, yet we can still see she isn't moving. But the angle changes back and suddenly the ID hangs freely, dead center, over the buttons. Moments later, as she turns to leave, it's again tucked in.

Factual error: In the situation room, Colonel Chase informs Leo that a CH-47 Seahawk helicopter was dispatched from the USS Monterey. Problem is, the CH-47 is called "Chinook" while the SH-60 is the Seahawk (of which the USS Monterey carries two). See: http://picasaweb.google.com/agbeko.Dzamesi/Aircraft/photo5029495094968996146 for photo of an SH-60B Seahawk landing on the USS Monterey.

Continuity: During the beginning before the opening credits, C.J. is briefing the press corps on the bus. In the outside shot of the bus, C.J. has her left arm resting on a rail, towards the door. When the shot changes to inside, C.J. has her right arm on a rail towards the driver.

Audio problem: As Charlie leaves the Oval Office, he pulls the door behind him. When it stops moving, the audio suggests it has been closed fully ("ka-chunk"), yet it's obvious it has not been closed as we can still see the outer office's curtains at the right of the screen, confirmed further when C.J. steps forward and the camera pans right to show the entire door frame area, and the door open quite a bit.

Factual error: Leo asks how long it will be before the missile system being tested will hit the target, and is told "two minutes, ten seconds". He decides the President should see it, and leaves to fetch him. But doing so results in them both arriving back in the room exactly 3 minutes later. 7 seconds after that, they are told there are still 50 seconds to impact (but it should have occurred 57 seconds ago). After the 50 seconds pass, Leo states the impact will occur in 20 more seconds, and the moment of expected impact does pass at that time. In all, 4 minutes, 16 seconds pass from when "2 minutes, 10 seconds" to impact was announced.

Audio problem: During the blackout, Donna and Josh sit together. The scene begins with the camera looking out the window, panning right to reveal Donna as we hear her finish saying, "You know what I'm surprised about?". But her mouth isn't moving at all until she begins her next sentence, and it's visible when we're hearing "about".

Other: In a scene with Leo and the President, Toby confronts them about the fact that there was no clear person in charge while the President was in hospital after being shot. He references the shooting as taking place 'last May'. However, in an earlier episode, 'The Midterms', there is a title card that states the date as August 14th and in the scene that follows there is discussion about the staff job approval in which CJ states, 'A week ago the job approval is at 51, we got shot at and its at 81.' This would mean that the shooting took place in August not May.

Revealing: Oliver Babish's office has windows in a location it can not possibly have them. Jed and Leo are in continuous conversation as they leave the 'normal' West Wing set at the end of a hall (See http://www.whitehousemuseum.org/special/wwtv.htm where the words 'Press Briefing Room' are - that's where they turn to their right). They walk a few steps then turn right again and ahead of them is Babish's office, with windows straight ahead. If this had been a single continuous set, Babish's office would be located in the stair area to the left of the press briefing room, and the windows would offer a view of the hallway that runs between the lower corners of Leo and C.J.'s offices (seen at 3:36), not the outside world.

Deliberate "mistake": This show is famous / infamous for having many long conversations between characters that are walking the corridors of the West Wing of the White House. In this episode, the chat was long enough that more space was needed to complete the walk, so the actors were instantaneously teleported to a different spot to lengthen the walk. Using http://www.whitehousemuseum.org/special/wwtv.htm as a guide, Pres. Bartlet and Leo leave the Oval Office, pass through the Presidential Secretary's office, turn left, passing between the Roosevelt Room and the Chief of Staff's office. At the end of the Roosevelt room, they turn left through dark wooden doors that are open. Instantly, the actors are at the next junction higher on the map (no wood doors), as if they'd just passed between the Roosevelt room and the Communications Bullpen, and they continue (downward on the map) thru the intersection where they original turned (watch for the doors after Leo says "You wouldn't understand").

Visible crew/equipment: As Bartlet enters the Oval Office, Babish stands waiting inside. The shadow of the panning camera darkens Babish's face considerably as it moves right to left.
