When Monsieur Bordeaux (David Wayne) is going into the utility closet on the 10th floor of the Hawaiian Regent Hotel to tap the telephone lines, a closeup of his hands reveals that he is not wearing gloves. Then he enters the room, sets down his case, and opens the service panel for the telephone, and is suddenly wearing rubber surgical gloves during all of this activity.
Early in the episode, McGarrett writes the characteristics of the thief "S. R. Horus" on a portable chalkboard in his office, with headings "Conscious M.O." (i.e., method of operation/modus operandi) and "Unconscious M.O." Although words are added to the original lists at various times, the handwriting that is already on the board changes over the course of the episode (for example, the "w" in the phrase "wears gloves" and the "o" in the second "M.O."), indicating that the board was completely erased and re-written to try to mimic what was already filmed.
When the thief is dressed in a security guard uniform the shoulder patch says Oaks Security Co. but the metal letters on the collar say HGS, the same as the Hayes Guard Service uniforms used in other episodes in the series.
When Five-0 is monitoring the room, the picture on the TV monitor is color, but in one instance the reflection of a snowy black and white screen can be seen on the desk where it is sitting.
The courier asks the thief if he is Atwood, but in the next scene he tells McGarrett he could have sworn the thief was Atwood because he looked just like him. Since he did not know Atwood as evidenced by his asking him his identity, he could not later say the thief looked like a man (Atwood) he had never seen before.
Johann Strasser's character is referred to as "Strasser" in the dialog, but listed as "Chadway" in the credits.
Apart from basic grammatical mistakes, when the waiter comes to the table of the thief, he asks the thief if he would like anything more. The thief's answer does not follow. He answers "Thank you, it's all nice". The waiter asks again if the thief would like more champagne. The thief answers "Non, je suis fini". He is in fact saying that he is dead. He should have said, "Non, j'ai fini" to say that he has finished eating.
