There was a pilot shot for the show, but to the best of my knowledge the
pilot was never broadcast and to the best of my knowledge is not available
for sale on video. For the pilot Lori Rom was cast as Phoebe Halliwell,
and another actor was cast as Andy Trudeau with the other cast members
being largely as we knew them in first season. Copies of the pilot were
sent out to some members of the press, so anyone who is determined to see
this should with some effort be able to track down a copy (start with the
likes of eBay).
13. Will there be a season 6? (Charmed)
Yes, it has been announced that there will be a season 6.
