Can any one help me to find a movie?

 Hmmm...

Maybe Robot Monster?

An archaeologist's child dreams of a creature who wants to destroy all of mankind.

This sounds more like a fantasy film than Sci fi. Could do with a little more info to go on. Can you remember if it was in colour or black and white? Although you saw the movie around 65-68, there could be some clues as to when it was produced. In what country did you view the movie ? Sometimes the accents on a movie can give away the country of origin.  

Thank you for your time . I can't remember a lot since is more than 50 years since then. Nakedlunch , i tried Robot monster , it was not the right film . Batchpool the country is Greece , i show the gilm in Athens. If this helps ,i can recall that it should be a film based on the atmosphere rather than in special effects. I remember that spacships were only dots in a radar screen . Yigrette Stark , there is no way to remember actors names , i doudt if i could even spell in English back then . (I know you think that there was very litle improvement since then). Any way if you can suggest some movies with similar case it would be helpful. Thank you again !!

I'm sorry I couldn't find anything that was like that, the closest thing I found that was somewhat similar was Quatermass and the Pit or also called 5 Million Years to Earth. Sorry about not finding it and you're more than welcome. Hopefully someone will come up with it for you.

Quatermass and the Pit seems very interesting movie. Espcialy the 1953 series. I watch it now. Thank you . After all it seems that the movie i remember had the same story like many others . 

@Stamatis   You're welcome
