TORONTO - It's shaping up to be an "I Dream of Jeannie" reunion at this year's edition of Fan Expo Canada.

The annual pop culture festival, set to run Aug. 26-28 at the Metro Toronto Convention Centre, will feature appearances by Larry Hagman and Barbara Eden, who starred on "Jeannie" in the 1960s.

Hagman, of course, also played notorious oil baron J.R. Ewing on the long-running night-time soap opera "Dallas."

Lee Majors, best known as TV's "Six Million Dollar Man," is also scheduled to attend, as is "Buffy the Vampire Slayer" and "Dollhouse" star Eliza Dushku and "Battlestar Galactica" alumna Katee Sackhoff.

Others attendees will include Marina Sirtis, who played Deanna Troi in "Star Trek: The Next Generation"; Tom Felton, known for his role as Draco Malfoy in the "Harry Potter" films; Anthony Daniels, who played C3P0 in the "Star Wars" films; Kevin Sorbo ("Hercules," and "Andromeda") and Sam Trammell of "True Blood."

The event will feature celeb presentations, autograph sessions and a science fiction masquerade party.
