A curious bit of news has come out via Cinematical that the Avengers film has cast Kevin Pennington to the role of a SHIELD agent named Wendell Vaughn, whom some fans may know better as the character Quasar. Pennington isn't a well known name at this point with only a couple of things under his belt that are due out but with the way Marvel is continually looking to expand on its characters and to try going for fresh faces for small characters that can be utilized later, it's not much of a surprise. Cinematical does note that we've heard the name before back when Ant-Man was being talked about as the man for that role.
In addition to that, some potential fun for those in the New York City area should be coming up in the next few months as word is getting out that:
During principal filming, SHIELD will be out in full force in NYC to recruit and find new members. Cast members on hand include Samuel L. Jackson (Director Nick Fury), Clark Gregg (Agent Phil Coulson), Cobie Smulders (Agent Maria Hill) and Kevin Pennington (Agent Wendell Vaughn). Fans will get the chance to meet the stars and get their photograph taken with them at the event.
