One of the more intriguing elements of Far Cry 5 is the story--which focuses on a cult called Eden's Gate in Montana, USA. The leader of the cult is Joseph Seed, a creepy and charismatic madman of sorts whose followers call him The Father. Actor Greg Bryk (Saw V, Netflix's Frontier) brings the character to life in the game (and the live-action short film), and from what we've seen and played so far, his performance is outstanding. He's chilling in how he believes his cause is the right one and will stop at nothing to get his way. The character is integral to the story, and Ubisoft knew it had to find the right person to play him to get the message across in the right away. As it turns out, Bryk was a late addition to the lineup, a fact that led to some amount of stress and scrutiny within Ubisoft. The game's executive producer, Dan Hay, thought the game might be in trouble.

Speaking to GameSpot, Hay said Ubisoft was able to build out the game's supporting cast with relative ease, but it struggled to find the right actor to play Seed. "We took a long time to find him. To be honest, it was a little bit scary because it went around in circles for a while. Everything hinges on finding the right guy," he said.
