Heads up about this film series (H/T: Glenn Branch). It looks nice, and could make a good framework for discussion, maybe chapter by chapter. The first chapter, “Taxonomy,” is described on Vimeo in this way:
Introductory chapter of a powerfully original film series about the science of evolutionary biology. The series is for a general audience and has particular importance for high school and college educators and students in all fields of biology. And for anyone who wants to know what life is all about.
Other chapters include “Nabokov’s Butterflies,” 
“The Cambrian,” and three different chapters based on Wallace. The main character (host, narrator, “script consultant”) is Andrew Berry at Harvard.
