Toban B. sent in a link to a clip of a 1935 Department of the Interior movie that includes a scene with African American conservation workers. I couldn’t find an embed code, so you have to click over, but the clip clearly illustrates the “happy-go-lucky,” dancing and singing stereotype of Blacks common to the era. The person who posted the clip says,

The racial stereotyping in this clip is appalling, but not surprising for a 1935 production. Hollywood films of that era also portrayed African-Americans purely for laughs. It was a rare film that showed black people as more than two-dimensional, and when they did – as Hattie McDaniel demonstrated in Gone With The Wind – Hollywood was ready to pat itself on the back.

Of course, Spike Lee’s movie “Bamboozled” implied that this type of stereotypical Black-man-as-happy-man-child-entertainer trope is still alive and well. He’s been criticized for his portrayal, of course, but it’s food for thought.
