The title itself makes us cringe.
Helen Bannerman's 1899 children's story would offend few people today, but we're more familiar with the knock-off versions with their derogatory racial caricatures. The very word "sambo" is a racial slur.
Sambo and his mammy are both drawn as racial caricatures. Their presence alone keeps this film off the TV airwaves, as do at least three racial gags:
*The mammy pats down a freshly-scrubbed Sambo with black powder.
*The mammy warns Sambo to watch out for the mean tiger: "He shore do like dark meat!"
* Sambo turns white with fear.
