I have the clear feeling and the vague memory I've seen *Annihilation* before or at least some scenes in other(s) movie(s) years ago.

Scenes I think I already seen in a movie or movies before:

 - Pool with a guy with giant worms inside;
 - Abandoned military base with information on a table;
 - Bear attack;
 - Place with people like plants;
 - Beach with crystal threes;
 - Suicide in front of camera using phosphorus granade; 
 - The hole inside the lighthouse; 
 - Final fight with the alien clone. 

I remember to have watched something similar in TV during 90s or 2000s. But I cannot remember the name of the movie(s), almost sure of that. 

Is Annihilation an original movie, a sequel or a remake?
