This film is painful to watch most of the time. However, it is so bad, that anyone with even a little taste in cinema will start howling with laughter. The director clearly used as few words as possible to direct this film, and the acting is truly awful, making this film unintentionally funny. Ted Wass actually does act in the first scene and in the last, both shot on the same airplane, leading me to suspect that those were filmed before he met his co-star, the truly inept Tanya Roberts. After meeting her, it is apparent that Wass realized just how bad an actress she was, and gave up trying, producing a monotone performance for the rest of the film. Tanya Roberts may have been good looking but her acting range is limited to one expression where she screws her face up in an effort to look like she is concentrating (I thought she might just have been constipated throughout the filming since that is what her one facial expression suggested to me). The best actress in this whole mess, Elizabeth of Toro is killed off only a quarter of the way through the film, which brings the level of acting way down. The production clearly was filmed on a shoestring budget where they couldn't afford to re-shoot anything. Even the casual viewer in the theater is able to spot the wire the model helicopter is being guided by when it crashes (your not supposed to be able to see that), and there is never any kind of a herd of animals on screen in this African jungle movie, just one of any type at a time. If you watch carefully you will see the occasional shadow on the ground which doesn't belong to any actor in the scene(it must be a crew member's). The plot is blindingly obvious with absolutely no surprises or dramatic tension. The script is also very poor, with cheesy dialog running throughout it, and you can predict lines and jokes far in advance of their being said. Actually, the limited script helps as it means you don't have to suffer through Roberts trying to speak. So go to the film and laugh at it, and learn what not to do when producing a movie.
