Some of his examples are ridiculous. Why compare Brad Pitt to some unknown instead of Tom Cruise or someone at least in the same calibre (Clooney, Damon, etc.)

Some of his examples are ridiculous. Why compare Brad Pitt to some unknown instead of Tom Cruise or someone at least in the same calibre (Clooney, Damon, etc.). And Spiderman to Silver Surfer? How about Batman and Superman? I think his point is to suggest that when things exist at the same moment the one that is considered number one drastically outperforms the number two - but even that assertion is tenuous at best.
