1. Fox originally wanted a successor to their first hit series, with Keyser telling Vulture, "The network wanted a companion piece to Beverly Hills, 90210, something that might be able to take over when it was done. [The idea was] 'Don't tell the babysitter that Mom and Dad are dead!'" But Keyser and Lipman were more interested in the darker reality of a family of orphaned children.
2. While Fox was hesitant, they agreed to the tonal shift, but had one issue: "We even had a conversation that the oldest sibling would be a girl, but the network said, 'No. No one would accept that,'" Keyser revealed, with Charlie ultimately becoming the head of the family.
3. Jerry O'Connell was this close to being Bailey Salinger, the second oldest sibling...until he couldn't resist going the sci-fi route in Sliders. Scott Wolf, of course, ended up in the role, and was actually the first of the siblings to be cast.
"We cast Scott first and we cast him on the first day," Lippman told EW. "He's such a warm person that he seemed completely right for the character."
