Hollywood, like any industry, has become increasingly creative in promoting its products, including the use of sneaky/innovative guerrilla and viral marketing tactics. For example, political advertisements for Harvey Dent have popped up on billboards in several cities (with a website that was live long before that) as part of the marketing campaign for The Dark Knight (Harvey Dent a.k.a. Two-Face will be played by Aaron Eckhart).
Then there was all that viral stuff surrounding the super secretive Cloverfield just before its January release. And who hasn't seen the Sarah Marshall-bashing websites and posters promoting the upcoming Judd Apatow-Jason Segel project?
I'm curious: do you think these tactics are effective ways of breaking through the advertising clutter?
