The creators of "The Boss Baby " have obviously been mining the playwright's gritty, foul-mouthed "Glengarry Glen Ross" to build the title character, a ruthless, capitalist-minded newborn with pupils the size of saucers who insists that "Cookies are for closers." To make the connection even firmer, they've hired Alec Baldwin to voice the baby, reprising in cartoon version his motivational speaker from hell from the 1992 film version of "Glengarry Glen Ross." An army of animators — no, really, the endless end credits are staggering to sit through — have been employed to make a 12-course banquet out of a whimsical board book by Marla Frazee, which introduced the suit-wearing toddler. Directed by Tom McGrath, the director of the "Madagascar" franchise, "The Boss Baby" is best when it riffs off other action films, such as "The Matrix," ''Mary Poppins," ''Honeymoon in Vegas" and "Raiders Of The Lost Ark," to name a few. The animation and sound effects are so superbly rendered — the fantasy sequences have an entirely different and nifty flavor — that a drop of drool or a puff of baby powder seems to have real texture and feeling. The Boss Baby," a DreamWorks Animation release, is rated PG by the Motion Picture Association of America "for some mild, rude humor.
