I have yet to watch the film I Am Legend, starring Will Smith, aka The Fresh Prince. Richard Matheson's source novel, though, is a great book.
There were two prior adaptations of the novel. In the 1970s, Charlton Heston essayed the role as The Omega Man, and though I loved ol' Chuckles, it was not nearly as good a film as Soylent Green, nor the first filmic adaptation, the 1960s version, called The Last Man On Earth, starring another of my all time faves, Vincent Price. Who could not love Vinny?
The shots in this black and white film are excellent, and that's likely because it was made at the height of Fellini and Antonioni-mania, in Italy. Price made every role he played better than it had any right to be. He brought intelligence and pathos to some of the silliest characters ever invented. That's a great actor. Watch the scene where he has to stake his infected dog, and then you see a blanket with a stake in it. But he was doomed, by his non-leading man looks, to B films. Watch the film, and the case against voiceovers is rent. This film makes excellent use of such.
