ABC surprised attendees during the Comic-Con panel for Marvel’s “Agents of S.H.I.E.L.D.” by screening the full first episode of the series, that premieres Sept. 24.

Episode played well with the several thousand filling the room, generating a rousing reaction and thunderous applause.

Episode makes many references to Marvel’s movies and comic book characters in “The Avengers” universe, and reflects the light tone seen in that film. Marvel sees the show as a way to appeal to fans but also bring in new ones.

Show’s cast, including newcomer Brett Dalton, and creators Joss and Jed Whedon were on hand, now considered rock stars to fans in the crowd.

“I really hated being dead,” said Clark Gregg, who plays Agent Coulson, who was killed in “The Avengers.” He expoused his love for all-things Marvel and his thrill to return. “And I get a plane,” he said. How he returns was not explained in the pilot.

Series recently began production on its full season. “Wait until you see episode two,” Gregg told the audience.

Joss Whedon reflected on his new cast and ability to create episodes that let him play with more Marvel characters. “I have that feeling I have not had in a long time,” he said. “I guess I’m a little excited.”
