It's never fun when a friendship goes awry, but it's doubly worse when there's quite a lot of money involved: Walking Dead creator Robert Kirkman has been sued by former collaborator and childhood friend Tony Moore, who drew the first six issues of the comic book, as well as dozens of covers after leaving the title. Moore claims that he was tricked into giving up his commercial rights to the series, which has, of course, gone on to wild fame as cable's highest rated TV show. "Each of these works was prepared by [Moore] and Kirkman with the intention that their contributions be merged into inseparable or independent parts of a unitary whole," the lawsuit reads. "[Moore] and Kirkman were thus joint authors and co-owners of the copyrights in these works." 

HBO's Luck, a drama about the big bad horse racing scene, has been warmly received by most media critics, but lax production standards have roused critics less concerned with quality acting and believable narratives. According to the New York Observer, two horses used in filming were euthanized following on set injuries, prompting PETA to put the HBO show on blast. "Perhaps if producers had considered the proved safety protocols that we would have suggested, these horses would still be alive," the animal rights organization wrote in a blog post from a few weeks ago. PETA may be controversial, but considering the generally accepted moral standard for animal safety in media production, its disappointment doesn't seem so histrionic. 

In the last few years, the Super Bowl has reached new heights of cultural saturation, setting and breaking the record for the highest watched TV broadcast not once or twice but three times, enough to make someone's dad rage about the shallowness of American attention spans, maaaaaan. So yes, this is not a new thing. But it's still eye-dropping to look at the audience numbers from last night's Super Bowl XLVI: 111.3 million viewers, beating last year's game by 300,000. That's barely 20 million fewer people less than the number of voters in the 2008 presidential election! Think about that, maaaaan.

Some 100 dancers took to the heart of Times Square in New York yesterday to participate in a Soul Train flash mob to honor the show's creator and host Don Cornelius, who died from an apparent self-inflicted gun shot wound this week.  Sad, but there were no tears. Disco grooves, afro wigs, bell bottoms, dancing and confused foreign tourists were the order of the day. 

Even if you’re not a football fan, there are reasons to get excited for Super Bowl Sunday. Wings, booze, Madonna, commercials in which Matthew Broderick tries to recapture his faded youth, and most importantly, the Puppy Bowl.  Last year, some 9.2 million people turned in to view the cuddly event. Let’s take a look at what you can expect from today's big game.

Channing Tatum hosted this week’s SNL. He was funny enough but the real highlights of the show came from the musical acts. Kristen Wiig visited Weekend Update as Lana Del Rey to defend the singer’s critically panned performance last week in what will hopefully be the last word on that.  Agreed? Agreed. Bon Iver showed how it’s done live with “Holocene,” and “Beth/Rest.”

Portlandia has been racking up the musician cameos this season, kicking things off with Eddie Vedder. Last night, St. Vincent’s Annie Clark, with an assist from Kyle MacLachlan, and Modest Mouse frontman Isaac Brock both turned up.  Take a look.

Abrams' Law states that J.J. Abrams must be working on a high-concept sci-fi project at all times, even it's been a little while since the fanboy auteur really wowed anyone with any of his original ideas. That said, NBC has just picked up a new pilot from the Star Trek director called Revolution, which is in development for a fall premiere. Though details are sparse, the show will follow "a group of characters struggling to survive and reunite with loved ones in a world where all forms of energy have mysteriously ceased to exist.” We've been overdue for a Lana del Rey documentary, it's true. (dies a thousand tiny deaths)

● Roseanne Barr announced Thursday that she has filed the requisite paperwork to run for the Green Party nomination, just as she said she would. "The Democrats and Republicans have proven that they are servants — bought and paid for by the 1 percent — who are not doing what's in the best interest of the American people," she said, impressing also that, "Mainstream media will be unable to ignore me, but more importantly they will be unable to overlook the needs of average Americans in the run-up to the 2012 election."

This year's Super Bowl halftime show, featuring Madonna, M.I.A., and Nicki Minaj, is pretty good compared to the usual classic rock dinosaur they trot out on the stage. But God forbid, what if they were suddenly unable to perform thanks to a hamstring injury or lightning strike? This 30 Rock animated short dares to ask that question, with a cartoon Jack Donaghy gathering three singers to audition for the hypothetically vacant show. Rather amusingly, he invites alt-country balladeer Ryan Adams, rapper/comedy star Childish Gambino, and dad rock supremecist Michael McDonald to make their best case. Via E!
