"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."
