Men in black III coming soon

It's been 8 years since the alien fighting duo have kept the skies safe from the third kind, but they're coming back, and they're going back...in time?! Will Smith's character, Agent Jay will be sent back to 1969 where he will team up with a (much) younger Agent Kay (previously Tommy-Lee Jones' character), played by Josh Brolin. They'll be fighting a real bad biker named Yaz (played by Jermaine Clement?) who will be trying to kill the younger Agent Kay so that the world gets destroyed in the future - kind of a Terminator-esque idea... I'm sure there will be lots of laughs and race-related problems that Agent Jay will encounter back in 1969 and there is sure to be a ton of cameo's as well! Yoko Ono, Jimi Hendrix, Fidel Castro, Kareem Abdul-Jabbar and of course, Andy Warhol!
