When the photographer is making the movie of Pollock, he "zooms" in on the shoes. But the old 16 mm camera he is using has a turret with three fixed lenses; thus, he should not be able to zoom. All his other shots are as expected from fixed lenses of different focal lengths.
As the documentary filmmaker is filming Pollock painting, Pollock's footwear changes from "painting boots" to shoes and back to boots.
In the 'love scene' between Jackson and Peggy Gugenheim, Jackson lays in between Peggy's legs. In the next (reverse) shot, he is now outside (straddling) her legs.
When Jackson and Lee first go out to the barn, they discover that it was being used for storage and that, if cleaned out, it might make a suitable studio space. In reality, Jackson and Lee moved the empty barn to improve the view from the upper windows of their house. After moving the barn, Jackson started using it as a studio. This was probably done for the reasons that, since they were shooting on location, and moving the barn would have not only been much more expensive, it would have been illegal as it is a historic landmark.
When Jackson was moving into their fixer-upper cottage in the Hamptons, the couple is outdoors in the yard. The time of year is late fall as the trees in the background have no leaves. At this time of year, the song of a bird (wood thrush) would not be heard, since a wood thrush sings during spring and summer months for territorial reasons. Though this bird may still be present in the wooded area around the Hamptons, it would not be singing as such.
When Jackson turns the radio on, it comes on instantly. Old valve (tube) radios need several minutes to 'warm-up' before anything is heard.
In the 'love scene' between Jackson and Peggy Gugenheim, she says the word 'wait' in Greek.
People say many things when excited or passionate; there is no rule against speaking a few words in an unexpected tongue.

When Lee asks the man to carve the turkey, he goes through the motions of cutting it, though the knife never touches the meat.
A post-1958 Chevrolet truck (with four headlights) can be seen when Pollock takes the sick dog to the veterinarian in 1956.
There is a camera shadow on Jackson's face as he starts the mural.
There is a boom mic shadow on canvas as Jackson works on the mural.
