Question: Which film came out earlier, Call Me Kuchu or An Otter Study?
Sentence (from "An Otter Study"): The film provided a novel treatment of the creature, which had previously appeared on film only as the victim of hunt films, with the unique underwater footage, shot by a cameraman behind glass in a tank concealed on the bed of the river in the opening scene, and a concluding scene, excised from the surviving print, in which it escapes the hunters.
Relevant evidence: No
