I don't recall the exact scene, but wouldn't the different relative centers of mass, and the corresponding difference in distance from the black hole cause some drift. I assume it would be slow. Possibly VERY slow, so it likely wouldn't look like falling, but I think they would separate, right?

I read that as you fall into a black hole, there comes a point where the gravitational difference between your head and toes would be large enough to rip you apart. (Not that you wouldn't have other problems anyway :-) )

If they're as close to a decently-sized black hole as dramatic movie pictures require, I suspect they would be close enough for the separation not to be gentle at all, assuming their individual limbs wouldn't separate.

I haven't see the movie, but this only makes sense if the spacecraft is actively using thrusters, and the human obviously is not.

I recall a distinct lack of spaghettification.

they were spinning, right?
