This comment in Space SE got me wondering, and I can't think of a counterexample.

Especially since Hollywood seems to think that Mars has 1g (and all other planets too). :-)

When an object is dropped from height h, the time it takes to fall is t = sqrt(2h/g). Values for g on Earth, Mars and the Moon are about 9.81 and 3.72 m/s2 so dropping something from 1 meter takes 0.45, 0.71 and 1.11 seconds, respectively.

We have real video of objects dropped on the Moon from 1971 shown below, but my question is about Science Fiction movies that take place on Mars. What was the first movie with an object associated with a person being depicted to fall more slowly on Mars than it would on Earth?

"Associated with a person" means somehow in proximity to a being, perhaps dropped by them, as opposed to pure CGI explosions or things otherwise falling out of the sky.

    I've changed this to [history-of] and a first of question because the previous wording was borderline off topic just falling into the off topic side in my opinion.

    Asking about the first occurrence of something appearing in the sci-fi genre is perfectly on topic and fine here.

    Now I'm wondering - are that hammer and feather still there? We never see him pick them up again, and I'm not even sure how easy it is to bend over and pick stuff up off the ground in those suits. Might be a good SX.SE question... Jun 17, 2020 at 15:21

    I'm not an expert on recent movies and television shows set on Mars, so I can only wonder whether the answer to what movie first showed objects falling slowly on Mars might turn out to be some movie made in the year 2030! Jun 17, 2020 at 15:24

    @uhoh While entertainment shouldn't be important, it is one of main ingredients for HNQ. I'm afraid this Armageddon question didn't do it - not enough clarity/brevity... and fun. Pointing out how improbable is such event would maybe help a bit.
