Coordinates off-set logistics: creates call sheets, manages 15–25 daily arrival times, supervises background casting of 20–200 extras per shoot day.
Technical Details
The Second AD works with specialized software like Movie Magic Scheduling or StudioBinder to generate call sheets that include arrival times, location details, weather forecasts, and emergency contacts. On large productions, they coordinate 15-25 separate arrival times daily for different departments. Their radio equipment operates on separate channels (usually channel 2 or 3) to distinguish between coordination and artistic communication. Background casting typically involves 20-200 extras per shooting day, whose costuming, catering, and legal processing the Second AD oversees.
History & Development
In 1927, MGM introduced the hierarchical Assistant Director system to structure increasingly complex studio productions. In 1935, David O. Selznick systematized the separation between the First AD (creative support) and the Second AD (logistical execution). The Directors Guild of America first precisely defined areas of responsibility and minimum wages in 1965. With digitalization starting in 2000, the focus shifted from paper-based to cloud-based coordination systems.
Practical Application in Film
On "The Dark Knight" (2008), Second AD Josh Robertson coordinated over 300 background actors daily for the Chicago sequences and organized complex street closures with 48-hour advance notice. For "1917" (2019), Second ADs created minute-by-minute call sheets for the continuous long-take sequences, requiring the synchronized positioning of over 200 crew members. The typical workday begins 2-3 hours before shooting starts with location preparation and arrival coordination.
Comparison & Alternatives
Unlike the First AD, who provides direct creative input, the Second AD focuses on logistics and coordination outside the immediate set. The Third AD specifically handles background direction, while Location Managers manage spatial aspects. On low-budget productions under $500,000, a Script Supervisor or Production Coordinator often takes on these functions. Streaming productions are increasingly relying on digital coordination tools that automate traditional call sheet creation.
