The person credited as Reporter #1 in episode 7 of RINGER once did a fang-baring ad for TRUE BLOOD, although she has apparently never appeared in that show. (video on Sarah Michelle Gellar Pages.)
Emily C. Chang is also in "nightdreamblues", a film about a birthday reunion of three childhood friends. Her character’s name is Bonnie Yen. The film’s title is entirely in lowercase; that’s not a typo. Also in the cast is Diana Lee Inosanto, who was one of the stunt doubles for Sarah Michelle Gellar on Buffy the Vampire Slayer.
She will also be in another film, CRUEL WILL, which is about a father who harasses his daughter’s husband from beyond the grave. Another castmember of that film is Spencer Garrett who was in Star Trek twice, first as a man persecuted because of his partial Romulan ancestry in Next Gen, and second as an intelligent hologram in Voyager.
