During an interview with the “Slick & Thick” podcast, Ethan Suplee, who portrayed Randy Hickey, revealed that, ultimately, the cancellation was due to communication issues between NBC, the show’s network, and Fox, the show’s studio.
“We were a hit. And the network called the studio and said, ‘We want to license the show for another year,’ and the studio said, ‘Well, we want more money. We want to renegotiate our deal with you.’ And the network basically did not respond for two weeks,” said Suplee. “And then the studio called back and said, ‘We’ll take your deal,’ and the network said, ‘Too late.’”
Looks like plain old incompetence killed the show.
