Alien franchise misconceptions

After reading extensively
over at Avpgalaxy and Valaquen's Strangeshapes Blog I have realized that there may be a few misconceptions.

1

Ridley Scott is not the reason HR Giger was brought into Alien. It was Dan O'bannon that insisted he was used and due to that Ridley took a look at his work which prompted him to agree. If I am not mistaken Ridley threatened to walk if Giger wasn't used so Impressed was he. But the initial idea came from O' bannon.

Ridley had a very big part in why Alien was a good movie but he was not the sole reason why the movie was so great. Ridley Scott is a great director no doubt and a highly intelligent man who knows more about movie making that most people will ever know. But people forget that the people who made Alien were all very talented Individuals. O'bannon was a writer an actor a director and was a very good artist as well. Ronn Cobb was also a highly skilled person. Alien was as has been stated a collaborative effort. I am not under cutting Ridley. Also Giler and Hil was responsible for including Ash as the android.

Remarks.

So if these people were so talented why didn't they stay on for a second movie?

Well I have read that O'bannon said that there was a lot of ill feelings between the crew the not sure exactly what about.

Its a pity.

So they wouldn't rejoin for a sequel even if asked. Iam guessing that's why They never asked Ridley to direct.

Could be wrong.

Also the management had changed over at fox. And they probably wanted to make their own mark.

Are there any things that you feel people are not getting correctly about the Alien franchise? Please share it.
