Only one day after making a go at a new night, the staff of Threshold got word that their show is cancelled.

Threshold, the rookie CBS sci-fi series featuring the talents of several Star Trek alumni, was moved to Tuesday nights from Friday in attempt to build an audience. Apparently ratings after only one try, even during a holiday week, were not at the levels the network was looking for in order to keep the show going.

According to Zap2it.com, the show has been pulled from the schedule "for at least the next few weeks." However, staffers at the Threshold production offices here on the Paramount lot confirmed that the show is indeed cancelled, even though as of today (Monday) they have not been instructed to clear out.

Of 13 episodes produced, nine have aired. Whether the remaining four will see the light of day is unknown at this time. Zap2it notes, "With midseason shows looming, that could be it for the show," but could not confirm that with CBS.

Threshold co-stars Brent Spiner ("Data") and is executive produced by Brannon Braga. The creative team also includes former Star Trek: Enterprise writers Mike Sussman and Andre Bormanis.

Competition has been fierce this season, with a plethora of new sci-fi/paranormal series vying for the primetime audience. Night Stalker has already suffered the axe. But two other alien-invasion shows similar to Threshold — ABC's Invasion and NBC's Surface — have been awarded full-season pickups.
