O Brother, Where Art Thou? (2000)

"The film O Brother, Where Art Thou? is unlikely to restore them to the ranks of the mainstream, but it reaffirms their status as first-class jesters of the fringe."

Occupation: Dreamland (2005)

"The portrait that emerges is of proud and articulate recruits who are also young, often undereducated and usually underemployed."

Ocean's Twelve (2004)

"They make the Rat Pack look like a chain gang."

Of Time and the City (2009)

"All the images are stunning, but the film's star turns belong to the children who gather on front stoops and play among the city's derelict buildings."

Office Space (1999)

"Hits the mark with a resounding thwack as it skewers stupid memos, corporate cutbacks and mealy-mouthed consultants."

Old Dogs (2009)

"Williams is encouraged to supercharge his silliness, Travolta plays straight man and the kids are relegated to background noise."

Old School (2003)

"You may not respect yourself the morning after seeing Old School, but that doesn't mean you didn't have a good time the night before."

Oliver Twist (2005)

"Beauty and hateful ugliness meet in extraordinary harmony in Roman Polanski's Oliver Twist, fitting for a story that is a study in obvious contrasts."

On the Line (2001)

"A flawed and formulaic but watchable little fable about the pursuit of true love."

Once in a Lifetime: The Extraordinary Story of the New York Cosmos (2006)

"An energetically told tale, with eccentric characters to spare and a nostalgically bittersweet tone."

Once Upon a Time in the Midlands (2003)

"At its best, the new film by Shane Meadows suggests works by British social realist Ken Loach and Scottish social satirist Bill Forsyth, with a through-line from Mike Leigh's dysfunctional family tale Life Is Sweet."

One Night at McCool's (2001)

"Zwart ... shows a flair for whipping disparate elements into a film noir-flavored screwball highball."

Open Range (2003)

"Costner doesn't seek to reinvent the classic Westerns as much as simply honor them. On those modest terms, he succeeds."

Open Water (2004)

"It is often too simple for its own good."

Or (My Treasure) (2005)

"Detail after detail, Yedaya charts the emotional push-pull between daughter and mother and their internal turmoils."

The Original Kings of Comedy (2000)

"The Original Kings of Comedy is all about truth -- about love, family, work and life."

The Orphanage (2007)

"What makes this bleak thriller, the feature debut by Juan Antonio Bayona, not like [other horror movies]? Partly, it is an ambiguous sense of portent that clarifies itself by growing more opaque."

The Other Boleyn Girl (2008)

"On-location exteriors throughout the English countryside, elaborate costumes, and colorful sets overrun with tapestries, mounds of food and large sporting hounds make this one of the most authentic-looking period films in recent years."

The Others (2001)

"Everything is designed to service a finale more complex than what preceded without it."

Outside Providence (1999)

"Outside Providence is the kind of film that, 10 minutes after the closing credits roll, you can't help forgetting."

Over Her Dead Body (2008)

"The quirky romantic comedy works largely because of good writing, and Rudd's deadpan delivery of same. That he can do so as slapstick erupts around him makes it all the funnier."

Overnight (2004)

"A quintessential cautionary tale, the documentary Overnight also happens to be funnier than just about every comedy released last year."
