In the opening scene, one of the intelligence agents examining the satellite photo confirms that there are '2 CVE's' (escort aircraft carriers), and '4 destroyers' in the Indian battle group. But in the situation room, the type and numbers of ships are flip-flopped, and the Chief of Staff reporting to the president says it's reported as '4 CVE's and '2 destroyers' (a rather large discrepancy given the circumstances).
While in the situation room, the camera pans across several people while clocks with times from across the world are shown in the background. When the camera passes behind one character, the leftmost clock changes from 7:33 to 13:35.
CJ's office is next to Josh's in this episode. In future episodes, it is on the other side of the bullpen and next to Josh is a very small break room.
When Josh is served the subpoena in the Lobby, it is a tri-folded packet. When the shot flips after he and Donna walk through the door the packet has an additional crease down the center.
When Charlie is talking to the President about taking his daughter out on a date Charlie's name tag is under his tie. In the next shot it is on top of his tie, and one shot later it is back under his tie.
Repeatedly, as in the title, we are told that the former British ambassador to India is named "Lord John Marbury," but C.J. tells someone on the phone on background that Marbury is an hereditary earl. If he is an earl, he would be "Lord Marbury," or "John, Lord Marbury," but not "Lord John Marbury," which is the form of title of younger son of a nobleman, not the holder of a title such as earl.
They repeatedly mention the Indian Navy as deploying multiple C.V.E.'s (Aircraft Carrier, Escort). However, the last Escort Carrier was scrapped in 1976.
Lord John Marbury is described as having been the "British Ambassador to India". As both the United Kingdom and India are members of the Commonwealth, their diplomatic missions to each other are called "High Commission" rather than "Embassy"; as a consequence, the head of the mission would be the High Commissioner.
Although India has operated aircraft carriers since the 1960s, they have never had more than two at once. At this point in time, only one, INS Viraat, was in service.
CJ describes Lord John Marbury as an earl. This is impossible, as the title "Lord John" indicates that he is the younger son of either a duke or a marquis. Leo also calls him "Lord Marbury" which is incorrect if he is Lord John; "Lord Marbury" would be used to address him if he were a baron or a peer (a peer is a nobleman of the rank of earl or higher).
While speaking to Mrs. Landingham, Josh replaces the cover to the cookie jar twice. But the second time is him returning the cookie uneaten when he realizes the gravity of what Mrs. Landingham has told him.
In the opening scene, it shows the action taking place at the Pentagon. Out of the window behind the actors, you can clearly see the Washington Monument with the Lincoln Memorial behind it. This view is not possible from the Pentagon.
The map in the Situation Room labels Pakistani-controlled Kashmir as "Jamu" [sic] and Indian-controlled Kashmir as "Kashmir". In actuality, the Pakistani-controlled region is composed of "Azad Kashmir" on the west and the "Northern Areas" to the north, whereas the Indian-controlled territory is the Indian state of "Jammu and Kashmir." ("Jammu" has 2 M's in it.)
41:45 The Oval Office central window behind Pres/Marbury shows a building with steps to a door and lit windows. There are no buildings that close to the Oval.
CJ tells Toby that she is just starting to be credible with the press. Since she's been on the job for a year already, it is unlikely that it would take her that long to gain the trust of the White House press corps.
The president makes multiple references to the Book of Revelation, incorrectly calling it the Book of Revelations. The president is known for his thorough knowledge of the bible, and for his attention to detail; he would be the first to point out such an error.
