SAN DIEGO (AP) - Joss Whedon is the busiest man at Comic-Con.

The 49-year-old multihyphenate visionary talked television on Friday and film on Saturday, then rounded out the four-day geek extravaganza Sunday meeting with fans and talking with reporters at the Dark Horse Comics booth.

The topics included a new season of his "Buffy the Vampire Slayer" comic book series, the possibility of a "Serenity" title, and the dual realities of the Marvel film and television worlds.

Whedon says the storylines of Buffy and his other Vampire Slayer title, "Angel & Faith" will intertwine in interesting ways when Season 10 begins. And while he doesn't have concrete plans for "Serenity," he's mulling ideas and hopes to push the much-loved but short-lived television series into the ink-and-pencil world.

Oh, and the recently revived-for-television Agent Coulson will not be coming back in his "Marvel's The Avengers" sequel.
