Rob Barber and Mary Pearson When Rob Barber and Mary Pearson met in December 2005, they quickly struck up a friendship.

"We both thought of ourselves as pretty punk with what we were doing with our solo projects," Pearson said last week.

Kathy Bates and Alfre Woodard in Tyler Perry's The Family That Preys Much has been written over the past 18 months about the death/irrelevance of film criticism in print media, as newspapers scaled back their movie coverage and Premiere stopped publishing a print edition.

Buckcherry When Buckcherry co-founders Josh Todd and Keith Nelson re-formed the band in 2005 after a three-year hiatus, they got an opportunity to basically start from scratch.

Julie Walters, Meryl Streep, and Christine Baranski in Mamma Mia! Mamma Mia! isn't a massive hit, but it has staying power. With $136 million in domestic receipts since its release on July 18, it's at ninth place in the summer's box-office race, yet it's been a steady earner. This marks the movie's eighth week in the box-office top 10 (and hence the Box Office Power Rankings), equal to Iron Man and The Dark Knight and one more than WALL•E, Kung Fu Panda, and Indiana Jones & the Kingdom of the Crystal Skull. That's pretty impressive however you cut it, but especially in the absence of a huge opening weekend.

This points out one of the flaws of our system : Box Office Power Rankings have no sense of scale. After 20 days, Ben Stiller's comedy earned $87 million domestically to Batman's $411 million. Christopher Nolan's movie received better reviews. Yet in the eyes of the Box Office Power Rankings, they could soon be equals. It just isn't fair, is it?

Punch BrothersChris Thile doesn't like musical boundaries, and the mandolin player seems to almost relish pissing off those who would prefer to pigeonhole him.

Reader issue #699 In the fifth chapter of his book Evolution for Everyone: How Darwin's Theory Can Change the Way We Think About Our Lives, David Sloan Wilson writes: "It turns out that something very similar to my desert-island thought experiment has been performed on chickens by a poultry scientist named William Muir."

That probably sounds odd.

Darwin's ape Given its scope and depth, one might expect that St. Ambrose University's Darwin Project started with a big idea. After all, 2009 is the 150th anniversary of the original publication of Charles Darwin's On the Origin of the Species, as well as the 200th anniversary of its author's birth. (Both he and Abraham Lincoln were born on February 12, 1809.)

Star Wars: The Clone WarsHow badly has George Lucas damaged the Star Wars franchise? At BoxOfficeMojo.com, The Clone Wars' revenues are being compared to Final Fantasy and TMNT - and after two weekends, it's losing to both.

vickycristina.jpgIt's not a surprise that Tropic Thunder unseated The Dark Knight last weekend after four-week reigns atop the box-office charts and the Box Office Power Rankings. Good reviews, some protests, Ben Stiller, and a white-hot Robert Downey Jr. will do that, although its $40-million six-day take has to be considered something of a disappointment in light of its $92-million production budget.
