The story seems to start at on 5/8/2010 on AvengersNews.com where it is reported that an "inside source" says that the young man has signed with Marvel Studios to play a character in the next "Avengers" film.
The news hits the big tme a few days later when on 5/11/2010 Comic Book Movie.com posts Pennington's Twitter tweets about signing a three-picture deal with Marvel Studios, and repeats speculation that the character may be Hawkeye/Clint Barton as a S.H.I.E.L.D. agent
Then on 5/15/2010, AvengersNews.com gives a list of eight characters, all
presumably S.H.I.E.L.D agents, that Pennington may potentially be
playing. Of interest to us here at Captain Marvel Culture are "Agent
Jones" and "Noh Varr." Agent Jones could presumably be
Rick Jones, Marvel Comics' all-purpose sidekick who spent years
swapping atoms with Captain Mar-Vell, going back and forth into the
Negative Zone. Jones also was sidekick to the Hulk and Captain
America, so it sounds reasonable that the character would be in an
Avengers movie.
The next day, 5/16/2010, a Spanish website, Blogdesuperheroes.es picks up the story.
Also on that day, AvengersNews reports that Pennington tweeted that his role will not be Clint Barton/Hawkeye, which leaves Rick Jones or Noh-Varr.
A couple of days later, on 5/29/2010,
sums up the story so far, adding the news that Jeremy Renner is talking with Marvel about playing Hawkeye. A tweet by Pennington is posted here, as is an on-line poll in which the viewers are asked whether they would rather see Pennington as Rick Jones or Noh-Varr. The results come in at 185-156 in favor of Rick Jones. There is also a very lengthy list of comments giving a wide variety of fan opinions on the subject.
On 5/24/2010,
That same dayComicbookmovie.com reports the AvengersNews.com news, highlighting the ambiguousness of which Captain Marvel it would be, and suspecting that since Pennington was going to be at San Diego Comic Con that year, that's when the announcement would be made. Massive passionate fan posts.
...and also on that same day, that same Spanish site reports the news, but does add
Genis-Vell to the possible Captain Marvels Pennington could play.
On 6/8/2010, AvengersNews.com reports that Rick Jones is one of four
characters Pennington may be playing in upcoming movies.
Then on 6/13/2010, , the "Celluloid and Cigarette Burns" blog speculates on the possibilities of a "Ka-Zar" movie with Pennington in the lead role.
On 6/18/2010, AvengersNews.com posts pictures of Pennington with a Marvel watermark and lists the roles he is currently speculated to be playing, and none of them are Captain Marvel-related.
Time passes, and on 8/23/2010
the Hollywood Spy blog suggests that Pennington might play the Human Torch in a reboot of the "Fantastic Four" franchise.
Summer turns to autumn, autumn to winter, the holidays come and go, and then more than a month into the new year, on 2/8/2011, Blastr.com Reports that Strahotski.com reported that Yvonne Strahovski from the spy comedy TV show Chuck will be playing Carol Danvers/Ms. Marvel. This rumor does not last long.
On 2/8/2011,
Gotham News reports that there was to be an event
in the springtime involving the casting and shooting of the Avengers
movie in NYC. Present at the event would be many of the lead actors,
including "Kevin Pennington (Agent Wendell Vaughn)."
The report cites Big Shiny Robot as one of the several sites that posted this information. Big Shiny Robot is skeptical of the source. Gotham news even posts an update that Marvel denies the whole business.
...and here is how the rest of the 'netoshpere reported and reacted to the news...

2/13/2011 Movieweb "The Avengers Will Not Feature Kevin Pennington" In this article a tweet from the man himself dispells all rumors. Apparently even imdb.com was convinced he would be doing something in the Avengers franchise.
As a sign that this whole Pennington rumor cycle was past its prime, most of the fan posts were moans about how the X-Men franchise was being ruined.
...and so the hopes of seeing any Captain Marvel in a motion picture have once again been dashed, and another actor rumored to play one is revealed to not be.
