"Marvel's Agents of S.H.I.E.L.D.," Marvel's first television series, is from executive producers Joss Whedon ("Marvel's The Avengers," "Buffy the Vampire Slayer"), Jed Whedon and Maurissa Tancharoen, who co-wrote the pilot ("Dollhouse," "Dr.Horrible's Sing-Along Blog").

In "Marvel's Agents of S.H.I.E.L.D.," a spinoff of Disney's blockbuster movie, "The Avengers, " Agent Phil Coulson lives again and Clark Gregg, the actor who plays him, couldn't be happier.

Coulson was thought to be dead -- the victim of a fatal stabbing at the hands of Loki in the big-screen film. So Gregg was thrilled to get a call from executive producer Joss Whedon telling him that the character would be resurrected for the TV show.

"I thought that guardian fellow had impaled me quite convincingly," Gregg told reporters Sunday at the Television Critics Association press tour. "It was quite emotional giving up a character and a long-term job. I asked if they wanted to shoot one more scene where he just grazed me. ... But it was clear I was dead and the character had a great run. I didn't think I was coming back."

Whedon said that Coulson's revival will be explained over "several episodes."

Whedon, who has his hands full with the next "Avengers" film, said he was drawn to "S.H.I.E.L.D." because of the humanistic elements embedded in its team of misfit agents.

"The thing that appealed to me is the idea of people who didn't have superpowers -- the person who didn't get the hammer," he said. " ... The thought that everyone matters."

Meanwhile, Ming-Na Wen, who plays agent Melinda May, is enjoying the chance to get physical.

"I am so proud to show off these guns," she said, flexing her muscle. "It's wonderful to raise the bar, to work out and do the training really needed to carry this character off. I think I'm going to be in the best shape of life. I hate to work out, but I do like kicking ass."
