Filmmakers behind the upcoming film "Good Boys"are being accused of blackface after they used makeup to darken the face of a child actor's stand-in.

The film's production company says it's common practice.

According toTMZ, sources connected to the film say 11-year-old Keith L. Williams' stand-in was on set last week in Vancouver, Canada with dark brown makeup on his face, an afro wig, and a fat suit. TMZ obtained photos of the stand-in in the getup while he appeared to be on break. The sight of his stand-in was reportedly upsetting to at least one person on set.

Other sources connected to the production company, Good Universe, reportedly told TMZ that it's "not uncommon for lighting purposes to match actors' skin tones," insisting that this is not a case of blackface.

Other experts say rather than using makeup, casting directors typically hire stand-ins who match the actors' complexions.

The "Good Boys" producers were  reportedly made aware that someone filed a complaint, and are in the process of addressing it.
