Quote:Evidently the makers of Yesterday Quest (1979) used a time-machine to travel to 1980 (Empire Strikes Back - Darth Vader claims to be Luke's father), and 1983 (Return of the Jedi - Princess Leia is revealed to be Luke's sister, Darth Vader is confirmed to be their father).
Good point. Funny thing about that is, it would be entirely possible for the reverse to be true. Vader's revelation was inspired by the Avengers story. I never underestimate the influence of comics on sci-fi TV and films. There is probably no more idea-rich tapestry than Marvel or DC comics.
Well, there are other older examples of this trope (Scaramouche).
