Two of the more anticipated panels at this year's WonderCon were the ones for J.J. Abrams' upcoming Star Trek and McG's continuation of the "Terminator" saga with Terminator Salvation . The two movies have a lot more in common than the fact they're the return of popular and long-absent franchises opening in May that both happen to co-star soon-to-be 20-year-old actor Anton Yelchin in key roles. Both movies decided to take advantage of the Wonder-Con crowds to world premiere their new trailers, which will precede Zack Snyder's Watchmen next Friday.
