The video shows a less wacky, more down-to-earth character, which just makes the whole thing so much sadder.
Speaking to Yahoo News, Farley's younger brother Kevin Farley explained how the Shrek character had to change.
Originally the Shrek character was a little bit more like Chris, like a humble, bumbling innocent guy. I understand why [they replaced him]. hey probably wanted to make Shrek 1, 2, 3, 4, 5, so… The studio needed to do what they needed to do. It was a bad time, bad timing… a tragedy. Mike did a great job with Shrek. He knocked it out of the park.
Chris Farley died of a drug overdose in 1997. He's had something of a revival in the past few months, with the release of I Am Chris Farley, a documentary about his life.
