Not that the improvement is all the result of Hemingway and Vance. The series is based on the nonfiction book "The Run of His Life: The People v. O.J. Simpson," by Jeffrey Toobin, a New Yorker writer and CNN legal analyst. Toobin, one of TV's sagest analysts, chronicled the backstage story of the courtroom battle. So it's not surprising that the film kicks into a higher gear as the so-called "Dream Team" for the defense comes together with the arrival of F. Lee Bailey (Nathan Lane), Alan Dershowitz (Evan Handler), Barry Scheck (Rob Morrow), Cochran and others.
