Q:Build a movie plot around this: Who is Jeff Portnoy? Jack Black; comedian in film
A:
A commercial depicts rapper Alpa Chino (Brandon T.

The first trailer shows action star Tugg Speedman's (Ben Stiller) latest film, Scorcher VI: Global Meltdown, a film so much like its five predecessors that even the trailer narrator sounds shaky about it.

The chaos is exacerbated when the film's pyrotechnics expert, Cody (Danny McBride), mistakes Cockburn's conniptions for a signal to set off several expensive explosions.Faux Access Hollywood clips reveal that Speedman's career has been on a downward spiral. In an attempt at Oscar-bait, Speedman had played the "retard" title character in a flop called Simple Jack, which is considered one of the worst films of all time. Meanwhile, much to the horror of...
