Lol. Dude. If you think green screens and CGI weren't super easy to recognize back in the 80's, you need to go watch some old movies that used it.
Also, yeah, Tron released 2 years earlier and had some CGI. There was even CGI way before Tron in movies. When I say there was no CGI, I'm saying there was no CGI that could fool even a 6 year old into thinking an animal was jumping off of a cliff.
As for the green screen thing.... Bless your little soul.
I don't use the fingerprint scanner cause cops can force you to unlock your phone by fingerprint, but not by pin or pattern.
