Titan Masters is filled with false advertising, Grax doesn't make any figure invisible and Xort doesn't do anything with gravity. Maybe they'll be in the Transformer toys of tomorrow which will be actual robots with AI.
Stargate sg1 was loosely based on the movie, it thrived on continuity it was impressive how old situations and solutions would come back in unexpected ways. Continuum had it's villain use the characters own solution in two previous episodes against them.
Like how Abydos in the movie is in another galaxy on the far side of the universe, but Abydos in SG1 is the closest world to Earth (and that was the only reason the gate could still get there) and even getting to other galaxies was impossible with the normal gates.
