From ComingSoon.net The Amazing Race 5 Gets the Green Light Source: Variety Monday, September 15, 2003 CBS has given executive producers Bertram van Munster and Jerry Bruckheimer the green light to begin casting for a fifth installment of the Emmy-nominated reality hit The Amazing Race. The network traditionally lets its reality producers begin casting only when there's a solid shot of a pickup or renewal, particularly when it comes to existing franchises. The Amazing Race 4, hosted by Phil Keoghan, was a solid Nielsen performer for CBS this summer in a difficult 8 p.m. Thursday slot, building ratings momentum as its season went along. Thank you God. I can't believe I got hooked on this show so late in the game. Glad it's getting another shot.
