Star Wars Empire Strikes Back, MIB, Matrix, Pacific Rim, Barbarella, Flash Gordon, new Star Trek one… for tv, Cleopatra 2525, ST: Voyager, Battlestar, ST:TOS, Lexx…there’s so many
The Fifth Element, Alien, Matrix (the first one of the series). I also loved space/alien themed tv series like Stargate(the original and Atlantis, Universe was not as good as the previous imo ), The X-Files and many others.
And of course there are so many other good sci-fi which are not space related, i really love Christopher Nolan moovies.
Blade Runner, Total Recall, Running Man, Tron (the original)
I’m a fan of the older generation of Sci-Fi although Moon totally did kick ass!
Bladerunner + Tron (original) + Ghost in the Shell Oh, you asked for favorite movie, not movieS, lol…
