El intruso de las profundidades

There is an oil rig in the middle of nowhere.Its staff is looking for oil but their mission is secret.A company geologist played by Joseph Bottoms is looking for alternative oil sources.One day he finds a bunch of small eggs.And creepy looking snake creature,who bites young worker prompting him to die.Whilst mysterious eggs are researched in the lab various oil rig workers begin to die...First of all I consider Peter Carter's "Rituals" to be one of the best and most fascinating survival horror movies of 70's. Peter Carter's "The Intruder Within" is clearly not as stunning.There are some effective moments of suspense,but the plot is silly as it rips-off "Alien".The creature effects are average at best.The atmosphere of isolation is well-captured,though.6 oil rigs out of 10.
