Jim Carrey and Terence Stamp in Yes ManYES MAN

It feels as though the teasers for Yes Man have been running since the first Bush administration, so I'm assuming everyone is aware of the film's 10-word comic premise: Jim Carrey always says "no," then learns to say "yes." If you're thinking the setup sounds an awful lot like the conceit behind 1997's Liar Liar, you're not wrong, and in his one-joke role as a depressed loan officer who decides to embrace life by acting against his natural impulses, Yes Man also requires Carrey to goose the proceedings with the sorts of rubber-faced buffoonery and "spontaneous" madness that the actor can pull off in his sleep. Unfortunately, that's exactly what he appears to be doing here.

Rachel Weisz and Ryan Reynolds in Definitely, MaybeDEFINITELY, MAYBE

If anyone's keeping track, writer-director Adam Brooks' Definitely, Maybe is the third romantic comedy of 2008 to climax with its protagonist taking a hasty cab ride to an inevitable romantic clinch and subsequent Happily Ever After. And that's about the only conventional element in it. I'm a little staggered by just how wonderful this movie is, as nothing about the film, from its cutesy setup to the presence of leading actor Ryan Reynolds, appeared to suggest anything more than the latest spin on a tireless (and, by now, tiresome) genre. Yet Definitely, Maybe is sensational, so smart and witty and refreshingly grown-up that, hours after seeing it, you may still find yourself in a great mood; the only times I stopped smiling at the movie were when I was laughing out loud.

Mel Johnson Jr.Though a familiar television presence through such series as The Practice, The Fresh Prince of Bel-Air, and Star Trek: Deep Space Nine - in which the actor played the Cardassian Broca in the program's final two episodes - Mel Johnson Jr. is primarily a stage actor, with more than 30 years of professional credits on Broadway, off-Broadway, and in regional theatres and touring productions across America; most recently, he portrayed Hoke Colburn in an acclaimed presentation for Hartford TheatreWorks of Driving Miss Daisy (which the New York Times called "a splendid 20th-anniversary revival").

Garrison Keillor, Meryl Streep, and Lindsay Lohan in A Prairie Home CompanionA PRAIRIE HOME COMPANION

One of the many glories of Robert Altman is that he never pretends to know everything there is to know about the characters in his movies, and doesn't expect his audiences to, either. In an Altman film, you may think you have someone all figured out, until a later scene proves that you haven't begun to understand what makes them tick; Altman is fascinated with the dichotomy between characters' public and private faces. (It makes perfect sense that he eventually filmed a murder mystery.) It sometimes seems that there's not much going on in an Altman movie, and audiences could easily assume the same about the director's latest, A Prairie Home Companion. But if you're as enthralled with character as the director is, and with the drama of actors gradually revealing character, his ambling, "plotless" films can be sheer bliss.

Tom Cruise in CollateralCOLLATERAL

Collateral's plot is so High Concept you can barely believe it hasn't been filmed before: A cab driver (Jamie Foxx) unknowingly picks up a hired assassin (Tom Cruise) as a fare, and spends a long, strange evening chauffeuring him from one execution site to another, all the while trying to prevent the killer from performing his rounds without, of course, getting himself killed in the process.

Halle Berry and Pierce Brosnan in Die Another DayDIE ANOTHER DAY

In lieu of trying to detail the plot of the latest James Bond vehicle, Die Another Day - really, does it matter? - let me instead run a short list of what makes Lee Tamahori's outing my favorite Bond flick in, I dunno, at least 20 years:

Black Hawk DownBLACK HAWK DOWN

It has been widely reported that Ridley Scott's war drama Black Hawk Down, originally due later this year, had its release bumped up to qualify for year-end awards consideration and, in theory, serve as a balm for a country forever damaged by the tragic events of September 11. There's no reason to refute this, and there might even be a kind of self-serving nobility in Columbia Studios' decision, yet the film in question is a technically impressive atrocity, one that's perhaps even more heinous in light of last fall's terrorist attacks. Although based on true events and Mark Bowden's well-regarded book, Black Hawk Down is jingoistic, dramatically inert, and sometimes shockingly racist; expect nominations and awards to follow.

Denzel Washington in Training DayTRAINING DAY

In Training Day, Denzel Washington plays a character so far against type - a ruthless, volatile inner-city detective who just might be a sociopath - that the movie's opening 30 minutes give you a bit of a charge; you're willing to give this umpteenth good-cop/bad-cop tale the benefit of the doubt for the chance to see Washington showboat in a larger-than-life villain role.
