--Tropic Thunder (2008)--

A commercial depicts rapper Alpa Chino (Brandon T. Jackson) promoting his two brands: the "Booty Sweat" energy drink and "Bust-A-Nut" candy bar, while performing his hit song, "I Love Tha' Pussy". The first trailer shows action star Tugg Speedman's (Ben Stiller) latest film, 'Scorcher VI: Global Meltdown', a film so repetitive of it's five predecessors that even the trailer narrator sounds shaky about it.

Another trailer features funnyman Jeff "Fatty" Portnoy (Jack Black), playing the entirety of "America's favorite obese family" in the highly flautlent 'The Fatties: Fart 2'. The final trailer, entitled 'Satan's Alley', features Australian "five-time Oscar winner" Kirk Lazarus (Robert Downey Jr.) and Tobey Maguire (as himself) as two monks who begin an empassioned affair.

--I Am Legend (2007)--

Robert Neville is a scientist who was unable to stop the spread of the terrible virus that was incurable and man-made. Immune, Neville is now the last human survivor in what is left of New York City and perhaps the world. For three years, Neville has faithfully sent out daily radio messages, desperate to find any other survivors who might be out there. But he is not alone. Mutant victims of the plague -- The Infected -- lurk in the shadows... watching Neville's every move... waiting for him to make a fatal mistake. Perhaps mankind's last, best hope, Neville is driven by only one remaining mission: to find a way to reverse the effects of the virus using his own immune blood. But he knows he is outnumbered... and quickly running out of time.
