On a recent weekend in Las Vegas, the Hilton hosted one of the largest Star Trek conventions of all time. A legion of new Trekkies and Trekkers emerged to make their presence felt in the wake of the critically-approved blockbuster. The event beamed aboard its usual crew, including Starship pioneers William Shatner (aka the Priceline Negotiator) and Leonard Nimoy. In the unusual documentary “Mind Meld” both men reveal how their lives were forever changed on and off the Enterprise. Fans can brush up on the Final Frontier’s founding fathers while the waiting for the next movie to be made.
