and outlawed TV viewing, how did the terrorists watch the movies in the first place? Western movies have been restricted in some Middle Eastern nations for years.

For that matter, which movies portrayed hijacking airliners and flying them into buildings? Admittedly, there are some really bad movies out there ("Con Air", a series of explosions only loosely connected by a whiff of plot comes to mind) that glamorize violence and explosions, but I really don't see the connection.

The closest match to the events I can recall is a Tom Clancey book, "Debt of Honor", where a Japan Airlines pilot deliberately crashes his 747 into the Capital building, killing the President and most of Congress. That's how Jack Ryan got to be President.
