We realize there's only so much time one can spend in a day watching new trailers, viral video clips, and shaky cell phone footage of people arguing on live television. This is why every afternoon The Atlantic Wire highlights the day's video clips that truly earn your five minutes (or less) of attention. Today:

  • We admit that the first trailer for writer-director Cameron Crowe's We Bought a Zoo, scheduled to open in theaters December 23, isn't perfect. It's a trailer for a movie called We Bought a Zoo, you know? So demerits for the use of Sigur Ros' ubiquitous "Hoppípolla" (very strange, since the group is composing the film's original soundtrack) and letting Thomas Church give not one but two pieces of kind of sage, kind of obvious life advice in the span of two minutes. And what Leon from Curb Your Enthusiasm is doing as the real estate agent who sells Matt Damon the zoo is something only Crowe knows. Still, we hold out hope: In Damon, Crowe finally seems to have found an everyman, his Jack Lemmon, which he's always wanted, even when he was getting stuck with Tom Cruise instead. (Remember: Jerry Maguire was originally written for Tom Hanks. ) Also, the memoir by Benjamin Mee on which the movie's based goes off in a very, very unexpected direction. And it can't possibly be worse than Elizabethtown. [YouTube via Seat42F]

  • We've mentioned it before, but Will Arnett has the potential to be the best professional talk show guest of the new century. He's game for anything, is pleasant to listen to, has no problem when someone like, say, Jimmy Fallon trips all over his laugh lines, and seems at ease with having the kind of successful career that he can claim has been woefully unsuccessful whenever the mood strikes him. (John Ritter was the best at that.) This is all moot if Up All Night becomes a genuine hit for NBC this fall and Arnett becomes a crossover TV star. In which case, the search for the heir to George Segal will continue on. [Late Night with Jimmy Fallon]

  • The Descendants is dominating the early Oscar buzz, and why not? In just 45 seconds, George Clooney skims his pool, tries to feign interest in his older daughter, and tries to discipline his younger daughter. He only really gets the skimming part right. But he's Trying To Connect, which is important if you're under 60 and want to have a shot at winning Best Actor. [YouTube via Movieline]
