In his time as Green Arrow, Oliver Queen has faced a number of formidable foes, but perhaps none so powerful as Neal McDonough's Damien Darhk and Casper Crump's Vandal Savage. A new featurette for "Arrow" Season 4 takes a closer look at these two villains and their greatest strengths, as well as the way Oliver was able to finally overcome them.

In the video, McDonough, DC Entertainment CCO Geoff Johns and executive producers Andrew Kreisberg and Wendy Mericle go in depth about what influenced their take on these characters and why the experience of time offers an advantage like no other.

Starring Stephen Amell, David Ramsey and Emily Bett-Rickards, "Arrow" Season 4 is now available on Blu-ray and DVD.
