Now, fifteen years after the franchise began, we've got a glimpse of the impending third go-round:
One of my problems with MIB II was that Tommy Lee Jones spent half the movie as an amnesiac and without the counter-weight of Agent K, the movie became too much about Will Smith wishing he had a girlfriend. While Jones looks to be AWOL for much of the movie, I have faith in Josh Brolin to necessarily reign in Smith. Plus I love the idea of seeing all of MIB's "advanced technology" from the 1960s. Talk about a fantastic sandbox to play in.
That being said, the movie's budget and production has notably spun WAY out of control, so I wouldn't be entirely surprised if this turned out to be just as messy as the last one. We'll find out next Memorial Day weekend.
