The following article deals with the CIA's support of, involvement with, and "manipulation" of Hollywood.

Its pretty long and more thorough with recent films like Argo and Zero Dark Thirty, but the affect of 9/11 on Hollywood is repeated constantly.

But, whats particularly interesting is the specific notation and time spent on Ben Affleck's relation to the CIA:

"The long relationship between Affleck, a prominent Hollywood liberal, and Langley seems particularly perplexing. But the mutual admiration has paid off handsomely for all concerned."

"Brandon, the CIA’s man in Hollywood, was also a frequent presence on the set of Alias, the TV espionage series starring Affleck’s then-wife, Jennifer Garner. The series, which debuted in September 2001, reflected the pervasive paranoia of the post-9/11 era—that climate of permanent anxiety so beloved by national-security agencies. Created by the Hollywood powerhouse J. J. Abrams, who would go on to reboot the Star Trek and Star Wars franchises, the show featured Garner as Sydney Bristow, a CIA undercover agent who infiltrated a global conspiracy."

"In March 2004, the CIA announced that Garner—reflecting the growing merger between Langley and Hollywood—had filmed a recruitment video for the agency."

Now, the show Alias was obviously planned, scripted, cast, and filmed well before its debut on September 30, 2001. But the timing... well, its just a coincidence right?

But anyone remember the summer blockbuster of 2001, coming out on Memorial Day weekend?

Pearl Harbor  Starring Ben Affleck. Co-starring Jennifer Garner.

Wow, small world. And again, interesting timing.

It was also produced by Jerry Buckheimer, who is known to have worked with the aforementioned Chase Brandon (the CIA liason officer) on his earlier movie Enemy of the State, not to mention how his movie Top Gun is credited with pretty much establishing the whole modern Hollywood-USmilitary colaberation.  

Furthemore, the article mentions the CIA involvement in the tv show 24, which also, only coincidentially, came out in November 2001.
