3rd AD


Large-scale productions often distinguish between 3rd AD Floor | Base | Crowd.

The 3rd AD Floor is the right hand of the 1st AD on set.

The 3rd AD Base is the right hand of the 2nd AD.

And the 3rd AD Crowd is the right hand of the 2nd AD Crowd.


The 3rd AD Floor often has only a few days of prep, if at all. Normally the PAs answer to the 3rd AD Floor and take on various tasks under his/her guidance.

In the US the 3rd AD Floor is called the 2nd2ndAD. In Europe 2nd 2nd AD is another term for the 2nd AD Crowd.

The key tasks are the guarantee of processes running smoothly on set and assisting the 1st AD.

  • Ensuring that all departments are aware of the 1st AD’s instructions and commands, so that they can prepare and react in a timely fashion.
  • Supporting the 1st AD with regards to safety on set in collaboration with the Set Manager and the Locations Department.
