Once Upon a Time has many ties with LOST. Naveen is the last in a long line of LOST alumni to appear on a Once show. LOST actors in the cast of the original Once are Emilie de Ravin (Claire on LOST, now playing a major role in Once as Belle), Jorge Garcia (Hurley on LOST, has an occasional guest role as a giant on Once), Lana Parrilla (has a starring role in Once as Regina, the Evil Queen / had a guest role in LOST playing an Other named Greta in two Season 3 episodes — she was one of the two women who tied up Charlie in the underwater Looking Glass station), and Alan Dale (Charles Widmore on LOST, has a recurring guest role as King George on Once).
In addition, the creators of Once and Once:Wonderland were writers on LOST, and Once often tosses in LOST references to amuse people who are fans of both shows. I wonder if Once:Wonderland will do the same.
This is going to be the first time that Naveen will have a role on U.S. television in a television show produced in the United States since he played Sayid. His character on Once:Wonderland will be Jafar, the villain in Disney’s Alladin, and he’ll be appearing on Wonderland from the first episode, which airs on Thursday, October 10 at 8 p.m.
