DOCUMENTARY PREMIERE: In 2005, March of the Penguins, telling of the migratory and sexual drives of penguins, was a surprise hit, and solidified Morgan Freeman as one of cinema’s (and television’s) most in-demand narrators. More than a decade later, this sequel arrives, following the path of a new young penguin. This new film, directed by Luc Jacquet, was released last year under the title L’empereur.
