I actually really liked this movie. It has an all-star cast (Gene Hackman, Red Buttons, Shelley Winters), who deliver great performances, and has really good special effects for their day. The only thing I kept saying about Red Buttons character through the most of the movie was "Leave Nonnie! She is a wussy wench and is slowing all of you down!" Cuz every time they moved onto a new obstacle, she was a coward. Anyway, this movie, in my opinion, deserves 7.8 out of 10.
