If there was any doubt that the final full day of Comic-Con would measure up against the powerhouse panels on Thursday and Friday, it was most likely demolished the moment Don Cheadle demanded to watch the just-screened five minutes of footage from Iron Man 2 one more time, to the roaring approval of roughly 6,000 fans in Hall H. But Cheadle, Robert Downey Jr., Scarlett Johansson, Sam Rockwell, and director Jon Favreau were far from the only highlights of Comic-Con’s Saturday. Other memorable moments:

1. The team from HBO’s True Blood — Sookie! Eric! Bill! — sunk its fangs into some juicy season 3 teasers.

2. Lost exec producers Carlton Cuse and Damon Lindelof held court on their show’s final season, along with VIP guests Jorge Garcia, Michael Emerson, Nestor Carbonell, and Josh Holloway. Meanwhile, Ian Somerhalder, in town to promote the CW’s Vampire Diaries, told EW that he will return to Lost next season.

3. Later in the day, EW’s own Jeff “Doc” Jensen and Dan “Dan” Snierson — a.k.a. the hosts of blockbuster web series Totally Lost — cracked wise and hosted some special Lost VIPs of their own.

4. ABC screened the pilot for its upcoming sci-fi series V.

5. Woody Harrelson pulled double duty on panels for the apocalyptic disaster film 2012 and the self-explanatory horror comedy Zombieland.

6. Mike Judge and Jason Bateman showed off their new, Office Space-esque comedy Extract.

7. And the crew from NBC’s Chuck kicked out the jams and dropped hints about season 3.
