Easily the most enjoyable film version of a Jules Verne story "Five Weeks in a Balloon" never slows down it's pace. Awash with color, humor, adventure, exotic sets, and a balloon that looks like it came from the designer of the "Swiss Family Robinson" treehouse, the film keeps up a brisk pace, tells a simple story, and wraps things up in a timely manner. Other reviews mention the rich cast and still manage to miss major performances by Red Buttons and Peter Lorre (that tells you something about the cast). Irwin Allen at his best.
