Meaning: The quote by Ashley Scott, an actress known for her roles in various films and television shows, seems to be referring to the challenges and limitations of filming scenes that involve diving. It appears that the production team had to use doubles for some of the underwater scenes due to restrictions related to diving hours and safety protocols.

Filming underwater scenes can present unique challenges for production teams. Diving and filming in aquatic environments require careful planning and adherence to safety guidelines to ensure the well-being of the cast and crew. Additionally, the use of scuba equipment and the need for breaks between dives to prevent decompression sickness can impact the scheduling and execution of underwater sequences.

The mention of "certain hours that you can dive" likely alludes to the time restrictions placed on diving activities, particularly when using scuba gear. Divers are typically required to adhere to time limits for each dive to prevent the buildup of nitrogen in their bodies, which can lead to decompression sickness if not managed properly. This limitation may have influenced the filming schedule and necessitated the use of doubles for certain scenes to work within these time constraints.

Furthermore, the reference to "12 hours just for the air and stuff" could be related to the interval required between dives to allow the body to off-gas excess nitrogen absorbed during the previous dive. The interval between dives, known as the surface interval, is crucial for diver safety and is determined based on factors such as dive depth and dive duration. For recreational diving, a surface interval of at least 12 hours is often recommended to minimize the risk of decompression sickness.

In the context of filmmaking, these diving restrictions would have posed logistical challenges for the production team. Coordinating underwater shoots within the limitations of dive hours and surface intervals would have required careful planning to ensure that the scenes were captured safely and efficiently. The decision to use doubles for some of the underwater sequences may have been a practical solution to work within these constraints while maintaining the continuity of the film's narrative.

Overall, Ashley Scott's quote sheds light on the complexities involved in filming underwater scenes and the considerations that go into navigating the regulations and safety protocols associated with diving. It provides a glimpse into the behind-the-scenes intricacies of bringing aquatic elements to the screen and highlights the meticulous planning and coordination required to overcome the challenges of filming in underwater environments.
