Movie #1832: Miranda (1948, Ken Annakin)
Fellow goes fishing and comes back with a mermaid. The whole film is a series of scenes where they try and keep the secret that she's a mermaid. So, kind of a one note film but a fun one nevertheless.
The final shot is Miranda with a baby mermaid (merman) so it looks like someone found out about her being a mermaid and wasn't put off about it at all.
