Correct me if I'm wrong but didn't he say render farm? Isn't that lots and lots of high end PCs designed and dedicated for 3D rendering working together in parallel?

Yep, and it takes longer than an hour for most rendered films. Cars 2 took an average of 11.5 hours per frame, on a single render. Keep in mind each frame is rendered several times as detail is added. Transformers took nearly 40 hours per frame. It varies per movie based on the amount of detail they want in there, but it is much more than 1 hour.
