Agents Of S.H.I.E.L.D. Season 4 Poster, Gag Reel, & Screen Tests

Aside from confirming that Ghost Rider will appear in the upcoming season, Agents of S.H.I.E.L.D. panel at San Diego Comic-Con on Friday included a pair of screentests, a Season 3 blooper reel, and a Season 4 poster that was illustrated by Mike Perkins. Now, Marvel Entertainment has released all of it.

For the screentests, we get to see the earliest pairings of Iain De Caestecker and Elizabeth Henstridge (Fitz-Simmons) and Chloe Bennett and Brett Dalton (Skye-Ward). Right off the bat, you can tell their was a natural chemistry with each pair from the get-go.

As for the blooper reel, we get to see a lighter-side to the cast. Having to keep a straight face most of the time because they are constantly portraing characters in some sort of danger, it is refreshing to see them flubbing lines and being clumsy on the set.

Season 3 ended with a flash-forward to Coulson and Agent Alphonso "Mack" MacKenzie in the field trying to chase down Daisy Johnson, who went AWOL after Lincoln's death. Coulson has apparently stepped down as director of S.H.I.E.L.D.; meanwhile, transhumanist scientist Holden Radcliffe is preparing to introduce the world to the androids called Life Model Decoys.

Marvel's Agents of S.H.I.E.L.D. is executive produced and co-created by Joss Whedon ("Marvel's The Avengers," "Buffy the Vampire Slayer") and Jed Whedon & Maurissa Tancharoen, ("Dollhouse," "Dr.Horrible's Sing-Along Blog").

Marvel's Agents of S.H.I.E.L.D. is produced by Marvel Television and ABC Studios.
