doomsday machine (1976)

"I don't understand."
The Americans discover that the Chinese have developed a doomsday machine that can destroy the earth. This derails the preparations for a mission to Venus as the crew must try to save the Earth from destruction, with three of the crew being replaced by three women.
Be amazed who the women manage to maintain their beehives whilst in space, in this cheesy and cheap Sci-fi hokem.

jungle man-eaters (1954)

"Never turn your back on a hungry lion..."
Jungle Jim (Johnny Weissmuller) has to battle a despicable diamond smuggler, who has enlisted a a renegade tribe to drive other more peaceful tribes off their land.
Cheap and uninteresting.

tarzan and the slave girl (1950)

"these are good people."
The Lionians are kidnapping women with the aim of adding them to their harem, and help repopulate their village, which has been devestated by disease. Eventually they get round to Jane (Vanessa Brown) and a nurse (Denise Darcel)and Tarzan (Lex Barker) has to rush to their rescue, whilst defending himself from blowgun attacks from the Waddie tribe, disguised as bushes.
One of the best Barker Tarzan's, with comedy, adventure and suspense.

tarzan's magic fountain (1949)

"We go back now."
A pilot (Evelyn Ankers), whose plane went down many years previously, emerges from the jungle looking no older. All courtesy of a fountain of youth, hidden in a secluded valley. Hunters (including Albert Dekker), seeing this miracle obviously want in on the secret. Tarzan (Lex Barker) then has to come to the rescue when Jane decides to take them to the forbidden valley against Tarzan's wishes.
Baxter takes over the mantle from Weissmuller in what is a lesser entry in the series, but one that still lots of fun to watch.

the doomsday machine (1976)

"I can't get over it. Putting females together with the male animal in a cage like this. What are we supposed to do for the next two years, breed!"
The Chinese have developed a bomb capable of wiping out all life on earth, and plan to use it within days. In an attempt to counter this the US govt takes over a manned mission to Venus, replacing half the crew with women. So when the inevitable apocalypse occurs these people become the last humans in the universe...
A troubled production obviously didn't help to keep this film focused; as a partially complete film is then mashed together with scenes featuring new actors, to make one mess of a salvage job.
