The Loneliest Whale: The Search for 52.

An unusual whale call sends a filmmaker and scientists into the Pacific.

A whale heard calling at an unusual frequency has become a symbol of loneliness, even though much about the animal remains unknown. Filmmaker Joshua Zeman joins researchers searching for the source of that sound. Their voyage combines the practical challenges of tracking whales with a look at how people communicate, project emotions onto animals and affect the ocean’s soundscape.

Why it’s a little special

A marine mystery that gives scientific curiosity room to unfold, with whale encounters and questions about what researchers can learn from listening carefully.

PG
Parental guidance suggested

US film rating

The official US PG rating cites some unsettling whaling images, language and brief smoking. Historical hunting footage and discussion of whales being killed can be upsetting. Ocean noise, environmental damage and the idea of an isolated animal also feature. The scientific search contains uncertainty rather than a simple animal-rescue storyline.

Our notes are a starting point, not an age recommendation. G and PG films can still include intense moments. You know your family best.
