The filmmakers behind an upcoming comedy used makeup to darken the face of a child actor's stand-in -- a la "blackface" -- but the film's production company says it's common practice.
Sources connected to the film, "Good Boys" -- produced by Seth Rogen and Evan Goldberg -- tell TMZ ... 11-year-old Keith L. Williams' stand-in was on set last week in Vancouver, and wearing dark brown makeup on his face.
We're told the stand-in was also rocking an afro wig and fitted in a fat suit. Williams was on a break at the time, but our sources say the sight of his stand-in was upsetting to at least one person on set.
Other sources connected to the production company, Good Universe, tell us it's "not uncommon for lighting purposes to match actors' skin tones" ... and they insist this is not a blackface situation.
We've spoken to others in the industry who say their experience is, rather than using makeup, casting directors typically make a point of hiring stand-ins who match the actors' complexions.
We're told "Good Boys" producers were aware someone had filed a complaint, and they were in the process of addressing the grievance.
For the record, we're told the stand-in is a light-skinned African-American kid.
Our studio sources added, the child's father, "a longtime stunt performer himself, who is also on the set, is offended by the [complaints] being made regarding his son."
