The very pregnant Natalie Portman is making the rounds these days to promote her new movie that explores the question of whether there's any such thing as consequence-free sex. Let that sink in for a moment.

New and Noteworthy

'No Strings Attached' (R)

Starring:Natalie Portman, Ashton Kutcher, Cary Elwes, Kevin Kline, Greta Gerwig
Directed by:Ivan Reitman
What's It About? Portman and Kutcher play old friends who decide to have a purely sexual relationship -- no romance allowed. But of course, it's never that easy, at least not in the movies.
Why Should You See It? Portman lets her inner-'Black Swan' loose, offering the kind of raunchy, funny, grown-up performance that past roles have only hinted at. Kutcher remains a pro at light comedy. Veteran comedy director Ivan Reitman, whose work has felt sluggish in recent years, seems invigorated by these youngsters and their fresher, blunter take on romance.

Staying in This Weekend?

New on DVD:'Buried' takes a premise Edgar Allan Poe would have loved and updates it to the digital age. Ryan Reynolds plays a man trapped in a coffin, with only a cell phone and a lighter to keep him alive long enough to figure out how he got there and how to get out. If you're claustrophobic or not a Reynolds fan (he's onscreen the entire movie), skip this one. Everyone else, dig in. Buy or rent the DVD | More new DVD releases

Movie Homework: 'The Way Back' may be a stirring epic about a true-life escape from a World War II prison camp, but the definitive entry in the genre is still 1963's 'The Great Escape.' Also based on a true story (one that doesn't turn out quite the way you think it will -- this is not 'Hogan's Heroes'), it features a full rogue's gallery of Hollywood tough guys, some then-famous (Steve McQueen, James Garner), some soon-to-be-famous (Charles Bronson, James Coburn) teaming up to execute an elaborate jailbreak. If you've seen it, it's worth seeing again just for McQueen's legendary motorcycle jump. Buy or rent the DVD

On Our Netflix Queue: At the Golden Globes this week, Annette Bening referred to her husband as the winner of the Globe for the most promising newcomer of 1962. She was referring to Warren Beatty's memorable movie debut in 'Splendor in the Grass,' made when his future wife was just three years old. Beatty and Natalie Wood smoulder as two small-town teens whose romance is thwarted by the hang-ups (sexual repression, class tensions, greed and other hypocrisies) of their virtuous elders. Watch this movie, and you'll see why the Globe voters thought this kid was going places. Buy or rent the DVD

On TV:'Mamma Mia!' isn't exactly a cinematic masterpiece, but on a cold, January night with a bowl of popcorn, this summery, Greek Isles-set musical should make for a fine girl's night in. (And in your living room, no one can see you dancing along to the all-ABBA soundtrack.) Plus, it's full of people we never get tired of, including Meryl Streep, Amanda Seyfried, Pierce Brosnan, Colin Firth, Stellan Skarsgård, Christine Baranski and Julie Walters. You have three chances to see it; it's on TBS at 8PM on Friday, Saturday and Sunday. Check your local listings
