Luc Jacquet's 85-minute film, shot entirely in Antarctica, follows emperor penguins on their annual 70-mile march through winter temperatures of -58°F and 100 mph winds.

Malik Bendjelloul's Searching for Sugar Man (2012) delivers documentary cinema's most emotionally overwhelming revelation, earning the Academy Award for Best Documentary Feature in 2013 alongside a BAFTA and 14 other major prizes. The film follows two South African fans investigating the mystery of Rodriguez, a Detroit folk singer whose 1970s albums flopped in the US but became anti-apartheid anthems—and who they believed died by suicide on stage. Rodriguez died in 2023 as a cult hero on two continents, with the film grossing $3.7 million globally on a $277,000 budget.

Nominated for the Academy Award for Best Documentary Feature, it holds a 97% Rotten Tomatoes rating and won the 2017 Emmy for Outstanding Documentary or Nonfiction Special.
