Jolene Blalock ("T'Pol") is set to join Star Trek: Enterprise castmate Connor Trinneer along with an extensive lineup of Trek stars from all five series at Creation Entertainment's fifth annual Official Star Trek Convention in Las Vegas this August.

The 40th anniversary celebration at the Vegas Hilton — taking place Thursday through Sunday, Aug. 17-20 — will be headlined by William Shatner, Avery Brooks, Kate Mulgrew and Jonathan Frakes. The roster includes many familiar faces and some not-so-familiar ones. Diana Muldaur ("Dr. Pulaski," "Dr. Miranda Jones," "Dr. Ann Mulhall") returns to the convention scene after several years' absence. Robert Foxworth ("V'Las," "Admiral Leyton" and the titular android in Gene Roddenberry's "The Questor Tapes") makes his first appearance at a Creation convention, along with Andrea Martin (the first actress to play "Ishka").

To commemorate the 40th anniversary of the Original Series, producer Robert Justman will speak about his experiences on that groundbreaking series. Other unique guests include "The Trek Life" cartoonist David Reddick, author Robert T. Jeschonek and scientists Ronald Held and David A. Williams.
