OUTTATAKES ARE IN

The trendiest way to prove you've arrived as a Hollywood auteur isn't having your own mega-production deal, like Terminator 2 director James Cameron. It's releasing outtake-laden video versions of your movies exclusively on laserdisc-like James Cameron. For a $100 disc of Aliens, he restored 17 minutes of cut scenes and appended the entire screenplay, behind-the-scenes pictures, and info on how the effects were done. Other laser boosters who've $ put out deluxe discs: Martin Scorsese (Raging Bull), John Singleton (Boyz N the Hood), and Danny DeVito (The War of the Roses). But will the trend go too far? Barbra Streisand's Prince of Tides disc will even include rehearsal videos. C'mon, people-say ''cut'' already.
