That was Journey to the Far Side of the Sun. Made in 1969 by the same people who did the old marionette shows like Thunderbirds, Fireball XL-5, and Captain Scarlet. Roy Thinnes (from The Invaders) starred as an astronaut who went on a mission to the opposite planet .... where everything was "opposite." The human body was a "mirror image," writing and printing was "backwards." When the people there tried to rebuild a spaceship to help Thinnes' character return to his orbiting "mothership" a question arose as to whether electrical connections were also backwards (they shoulda used AC power 
), but I've forgotten what the conclusion of that conumdrum was 
. It's on DVD.
Not bas special effects in the movie.
<based on seeing it -once- 25yrs ago, combined with a memory that is...well, see below>
The conclusion is he dies.
The scientists at Planet X don't realize the polarity issue (neither does idiot astronaut), and when his "new" (hell, let's call it Levo-rotary") pod docks, there is a short at the mis-polarized interface return fails.
IIRC, the counnection was in the nose, and the front of the capsule looked vaguely Gemini-like.
Yeah...my brain is weird.
Also, if he had used a lightning connector or USB-C, he'd have been fine. Even with DC.
Correction! I was WAY off, it looked like a lifting body, not a Gemini. My bad.
