I added a page but I have a doubt about the naming of it:
http://www.impdb.org/index.php?title=L%27arnacoeur
As the « L' » is kind of like "The" in English, I guess I should have put it after the title ? (« Arnacoeur, L' »)
There is also an English (non-original) title for that movie, "Heartbreaker".
I haven't added it yet to the movie list since I thought that maybe you would like to rename the page first...
