If you thought Dustin Hoffman was a riot in Meet the Fockers, the inevitable sequel to Meet the Parents, wait till you see him acting even less restrained in the outtakes. The two-time Oscar winner, who ''started acting to do Shakespeare,'' drops trou, proudly announces his arousal, and passes wind with such schoolboy delight that even grim Robert De Niro, who reportedly last laughed in Cape Fear, can't help but bust up. Hoffman and Barbra Streisand are dynamic as Ben Stiller's flaky parents, but their chemistry is wasted on a paper-thin script.
EXTRAS A Focker Family Portrait, a cast sit-down with Matt Lauer, and a feature on prima donna Mr. Jinx. All yawners. But Hoffman's antics in many of the 65 bloopers and 20 deleted scenes especially his Travis Bickle impression almost (almost!) make you hope for another Focker family reunion.
