In the trailer bin, two December epics that I suspect will be pretty bad. First, newcomer Ed Speleers gets help from Obi-Wan-ish dragonrider Jeremy Irons in his crusade against the sinister King Malkovich in the new full-length trailer for Eragon (I haven’t read the book, but this screams Sci-Fi channel miniseries.) And the Mayan civilization enters its decline (no doubt the Jews have something to do with it) in the most recent trailer for Mel Gibson’s Apocalypto.
