From Netflix:

A picture is worth a thousand words — or is it? That’s the question prep school students must answer as their teachers egg them on in this diverting romantic comedy starring Clive Owen and Juliette Binoche as the instructors who spark the debate.

Finally, a date movie without cringing. Ever beautiful Juliette Binoche as the art teacher and ever devilish Clive Owen as the creative writing teacher not only battle through an entire film with fun multi-syllabic word challenges but also engage their respective students in a competition of words versus pictures. Each has problems: she has serious rheumatoid arthritis and he is an alcoholic plagiarist. Will he keep his teaching job and not alienate his son? Will she be able to continue teaching and painting? Stay tuned.

Sometimes the dialog is not appropriate for children.

And by the way, it is also a love story which you might as well enjoy.
