Stargate SG-1 star Amanda Tapping (Lt. Col. Carter) makes a cameo appearance in SCI FI Channel's upcoming original miniseries Earthsea, the network confirmed. Tapping will play the part of Lady Elfarran, a ghost who appears to the miniseries' main character, Ged (Shawn Ashmore), early on.

Tapping shot her brief appearance in July in Vancouver, B.C., working on a "teeter-totter rig" that approximated the appearance of her floating in air. Her image will be inserted into the scene with visual effects in post-production. The Earthsea production team had worked out Tapping's schedule with the Stargate producers to allow her to appear in the miniseries.

Earthsea, based on Ursula K. Le Guin's award-winning series of fantasy novels, stars X-Men's Ashmore, Smallville's Kristin Kreuk, Isabella Rossellini and Danny Glover. The four-hour miniseries premieres Dec. 13.
