Hal Douglas was the "in a world" movie trailer voice for so many years. His voice has to be one of the most recognized voices ever when you think of all the movie trailers, as well as radio and TV commercials for those movies, that his voice is heard on. You can actually see the voice in action in this clip for Jerry Seinfeld's "Comedian" in which he's making fun some of the more cliched movie-trailer lines. RIP Hal Douglas.
