If you loved Jack and the Cuckoo-Clock Heart, try A Mermaid in Paris
A bridge between a film you've already seen and one most people haven't. A Mermaid in Paris has roughly 3.7× fewer votes than Jack and the Cuckoo-Clock Heart — it's a deeper cut, not a mainstream recommendation. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Mathias Malzieu, and they sit in Drama / Fantasy / Romance territory. If that's the register that drew you to Jack and the Cuckoo-Clock Heart, the second film will land in a comparable space — through a different lens.
What A Mermaid in Paris is
Apparently mermaids now frequent Paris. A man rescues a mermaid in the city. It predictably gets romantic.
