It's a wonder this film was made at all. As Omar Sharif famously said (I'm quoting from memory, but this is close): "Say you are the man with the money at the studio. Someone comes to you and says he wants to make a film that's four hours long, with no action, no love story, no women at all, very little dialog, and no stars in the lead roles, and you want to go to one of the most remote places in the world to film it. What would you say?"
Fortunately, it was made, and stands to this day as the greatest epic ever filmed. The dialog is indeed sparse, but memorable. There's not a wasted word in this movie. There is action, but it's not the focus of the film, this isn't an "action" movie. O'Toole and Sharif were relative unknowns at the time, but this film made them international stars. There is indeed no love story. Lawrence is believed to have been homosexual, and that aspect of his character is hinted at in the film, but not really addressed (this was 1962, after all). They did in fact film it in the vast, remote Jordanian desert, and that desert is as much a character in the film as any of the actors. If there was ever a more beautifully filmed movie, I haven't seen it. To say the cinematography is breathtaking is to fail to do it justice. The DVD looks spectacular, you have to remind yourself constantly that you're looking at a movie filmed over 40 years ago. The sound has also been remastered, and Maurice Jarre's score sounds glorious. Don't listen to those who say Lawrence of Arabia is overrated. It's impossible to overrate this movie.
