Kaine le mercenaire

Unlike much bigger-budget movies such as Total Recall (1990) or Charlie, les filles lui disent merci (2007) this movie features a woman with anatomically correct multiple breasts, in this case four.

This does happen occasionally due to a mutation, but only along the Mammalian Lines - two arcs along the torso from the genitals to the forelegs (armpits in humans), on which the teats of all mammals occur. Any number of teats may form on any species, but the typical amount is twice the usual litter size (which is of course one in humans), and no breasts would ever form along a horizontal line.

The planet Ur has two suns in the sky, yet there are no double shadows.

Two suns are so far away that they don't present two light sources. It's not like two spotlights.

According to the "Technical specs" link for this movie, there are at least two different versions of this film, one clocking in at 1 hr 21 min (81 min), and a second at 1 hr 14 min (74 min). The second was only released in the United Kingdom and has been edited down to remove some scenes of violence.
