You could be forgiven for dismissing Lambert as the 'scared one', after all, Ridley Scott told Veronica Cartright that her character 'was the audience'.
The next overriding memory is usually - how exactly did she die??
But Lambert is the ultimate Cassandric - the person you should listen to but never do!
Here are Lambert's warnings:
Her reservations started with being picked as one of the search party - she knew nothing good was going to happen.
Telling both Kane and Dallas (several times) it was time to 'get the hell out of here' while they were searching for the source of the signal and whilst in the derelict - that was an important one!
Asking whether Brett was alive when everyone presumed he was dead - a bit of a reach I know as he's only kind of alive/turning into an egg in the directors cut, but still no one else considered it!
First suggesting they abandon ship and take their chances on the shuttle - completely dismissed at first, until it wasn't!
Although not a warning, she's the one who knows how to kill Ash once and for all!
I cant help thinking that if anyone else had offered the same viewpoints and perspectives, the crew of The Nostromo may have escaped the nightmare of the Alien (or avoided it altogether). And that perhaps she was dismissed or ignored due to the fact she spent a lot of the film in a blind panic or completely frozen with fear.
Maybe the bottom line is this, its not what you say, but how you say it.
