记录片儿

noun

documentary film; documentary movie (colloquial variant of 纪录片儿)

This is a variant form of 纪录片儿, commonly used in colloquial speech, particularly in Beijing dialect. While 纪录片 is the standard written form, 记录片儿 reflects the spoken pronunciation where 记 and 纪 are homophones (both jì) and the erhua suffix (儿) adds a casual, conversational tone.
