it's time for this thread, since the pilot is now officially picked up for a full series, and they have released a Teaser
and viral site
Clark Gregg reprises his role of Agent Phil Coulson from Marvel’s feature films as he assembles a small, highly select group of Agents from the worldwide law-enforcement organization known as S.H.I.E.L.D. Together they investigate the new, the strange, and the unknown across the globe, protecting the ordinary from the extraordinary. Coulson’s team consists of Agent Grant Ward (Brett Dalton), highly trained in combat and espionage, Agent Melinda May (Ming-Na Wen) expert pilot and martial artist, Agent Leo Fitz (Iain De Caestecker); brilliant engineer and Agent Jemma Simmons (Elizabeth Henstridge) genius bio-chemist. Joining them on their journey into mystery is new recruit and computer hacker Skye (Chloe Bennet). From Executive Producers Joss Whedon (“Marvel’s The Avengers,” ”Buffy the Vampire Slayer”); Jed Whedon & Maurissa Tancharoen, “Marvel’s Agents of S.H.I.E.L.D.” pilot co-writers (“Dollhouse,” “Dr.Horrible’s Sing-Along Blog”); Jeffrey Bell (“Angel,” “Alias”); and Jeph Loeb (“Smallville”) comes Marvel’s first TV series. “Marvel’s Agents of S.H.I.E.L.D.” is produced by ABC Studios and Marvel Television.http://www.wired.com/underwire/2013/05/ ... tv-series/http://www.facebook.com/AgentsofShield
There seems to be speculation around the web that J. August Richards
(who played Charles Gunn, a regular character in Angel), who is playing an unnamed character in the Pilot, and can be seen in the teaser jumping from a building unharmed, is actually Luke Cage.
He could just be a random indestructible person, but I doubt Whedon would give a small part like that to a seasoned TV actor that he has worked with so much in the past.
also here are some more stills from the teaser i found
