With only four days to go until a brand new season of Agents of S.H.I.E.L.D. is upon us, the cast of S.H.I.E.L.D. took to their Twitter accounts today to release the new cast promotional images. Interestingly enough, both John Hannah (Holden Radcliffe) and Natalia Cordova-Buckley (Elena ‘Yo-Yo’ Rodriguez), who are currently credited as guest stars, were included with the main group. Could they be upped to season regulars this season? After all, we did lose quite a few cast members last season. You can check out the new cast photos in the gallery below.


Along with the new cast photos, the S.H.I.E.L.D. Twitter account released yet another teaser for the upcoming season focused on Gabriel Luna‘s Robbie “Ghost Rider” Reyes. It’s a relatively short one, but for fans eager to see Ghost Rider’s debut on the series, it should help to build your excitement ahead of the season premiere on Tuesday.

Agents of S.H.I.E.L.D. stars Clark Gregg (Phil Coulson), Chloe Bennet (Daisy “Quake” Johnson), Ming-Na Wen (Melinda May), Elizabeth Henstridge (Jemma Simmons), Iain De Caestecker (Leo Fitz), and Henry Simmons (Alphonso “Mack” Mackenzie). The show returns for its fourth season on Tuesday, September 20th, in its new 10 PM timeslot.
