What does a TV series order establish?
Development means a project is being worked on. A series order means the buyer has committed to make a series; the announcement may also specify how many episodes it ordered.
Follow Lanterns from development to order
In January 2023, DC Studios listed Lanterns on its development slate. In June 2024, HBO announced an eight-episode straight-to-series order. The first announcement establishes that the project existed. The second identifies the commissioning network, the decision to proceed and the number ordered.
Does an order establish a premiere date?
No. An order, a production start and a premiere are separate events. Keep the announced episode count attached to the order date; use the eventual release schedule for how many episodes actually aired and when.
