If you somehow missed Superheroes: A Never-Ending Battle when it aired Tuesday, or you simply want to watch it again, PBS has made the entire three-hour documentary available for viewing online.

Hosted by X-Men Origins: Wolverine actor Liev Schreiber, the documentary by Michael Kantor features interviews with the likes of Stan Lee, Adam West, Lynda Carter, Michael Chabon, Jules Feiffer and the late Joe Simon and Jerry Robinson, and chronicles how comic books “were subject to intense government scrutiny for their influence on American children and how they were created in large part by the children of immigrants whose fierce loyalty to a new homeland laid the foundation for a multibillion-dollar industry that is an influential part of our national identity.”

All three episodes -- "Truth, Justice and the American Way," "Great Power, Great Responsibility" and "A Hero Can Be Anyone" -- can be viewed below.
