Visible crew/equipment: When Oliver jumps out of the window of Adam Hunt's office, you can see the safety rope at the bottom.
Other mistake: In the newscast at the beginning of the episode, they incorrectly broadcast Robert Queen's birth date as 1948. They use the correct date in Episode 2 when it is shown as 1958 on his gravestone. (00:02:25)
Continuity mistake: When Oliver drinks his tequila, the hand with which he holds the glass keeps changing.
