TBH I'm not entirely sure, as it came out the same year as Paramount's Star Trek: The Motion Picture (another coincidence, I'm sure), and was actually Disney's first PG film. I had read that it had been in development for years, and was supposed be shot using the same camera system as the one ILM used to Star Wars,…

I remember that as one of Ernest Borgnine's most "realistic" or grounded roles, and the FX were AMAZING. It's a shame it came out 2 years after Star Wars because it definitely had potential…
