In the show “Silo,” Rebecca Ferguson’s character uses unusual diving gear to operate an underwater pump. The gear functions differently than typical scuba equipment, as it delivers air directly into the lungs when bitten. This made breathing feel strange and difficult for Ferguson, which caused her some confusion. Sometimes, she had to remove the gear and swim up quickly, which is not recommended in real diving situations. Ferguson thanked the dive team for ensuring her safety during the shoot in a tank on set.
