Thank you for pointing that out BBL, and I guess you are right. Sorry. I think the guy in your photo was trying to point something out too!
Yeah, the “face huggers”. Very traumatizing to see on the big screen as a kid. Then of course what followed afterwards.
1st and 2nd ones. Especially the space marines in the 2nd one. “Why don’t you put her in charge” quote still has me In tears laughing
The 3rd one had potential, I heard they got bogged down with a bunch of setbacks when trying to make it and I don't know if that was some proto-CGI or what but whatever those computerized effects they use in a lot of scenes when the Alien is running look really fake.
