When I first saw this film, I had heard nothing of it, but with the cast it had, I was expecting a fairly decent film. Instead, I found the film to be rather poor in both concept and execution. I am not saying that it isn't worth a look, however. Charlton Heston and Jack Palance gave decent performances that could have belonged in a better film, as did Corin Nemic. Tim Matheson wasn't half bad, but the rest of the cast seemed to fall flat on their faces. The plot was so contrived that you could shoot a solar flare through the plot holes. Basically, this film has been done better as bigger asteroid films (like Armageddon and Deep Impact) so it is a kind of waste of time unless you are a die hard fan of the actors or sci-fi disaster movies. I also must mention that even though the film brags about the special effects being done by the same people as 2001 and Star Wars, their effects in those movies were far superior. In this film, the effects feel cold and detached, where as in those movies they are visually exciting and stimulating. I guess it would have helped, though, if this film had had a bigger budget. So, overall, I wouldn't recommend this film to anyone unless they were really bored and liked cheesy sci-fi disaster films.
