This is great, Gaumont is already looking for actors, the script is already there and being polished
The action happens mostly in France where the unwilling hero, a scientist really, finds himself having to track a giant frog that eats people instead of being eaten by them !
I don't have all the details, but he will be helped by some mysterious gringo james-bondesque guy in this task.
Turns out, the giant creature is the result of some terrible mutation of some otherwise inoffensive and delicious frog because of the radiations caused bu the US nuclear bombs tests
The mysterious gringo will help the french dude (who would otherwise just give up), explaining that it is his responsibility; as much as he loves his country, sometimes his country fucks it up and he has to fix it !
