"Better" than originals? Nothing comes immediately to mind. But I do very much like Rufus Wainwright's cover of "Across the Universe," from the soundtrack for the movie "I Am Sam," which features lots of other covers of Beatles songs.
As for the new movie, "Across the Universe," directed by Julie Taymor -- sorry but I have to disagree with the previous post in favor of this movie. I found it charming for about ten minutes, then it started to take itself too seriously and lapsed into wretched excess. The director kept trying to force the Beatles' songs to fit her concepts, and too often it just didn't work. The cover of "Come Together," transformed into a hallucinogenic "Uncle Sam wants you" recruiting fantasy, went so far over the top that it hit bottom.
