An Exercise in Fatality - S4-E1
Visible crew/equipment: When Janus parks his car at the health spa's service entrance, the reflection of filming equipment, including a large spotlight and the location's 9-bank array lighting, is visible on the car's surface. Then Janus lets himself in with his master key. (00:10:30)
Other mistake: In the opening of this first series dedicated to Lupin, Fujiko Mine is riding a motorbike with the poorly romanized brand "RUPIN III"
