Technically movies for The Hobbit, but isn't the purpose of All Media Types to cover both if need be? (I'm just curious, that's why I nominated them that way). But yes, technically Frerin/Eowyn could be considered a crossover of LOTR and The Hobbit, though Frerin was never really a character in a book since he was dead by the time everything happened. They are just both Tolkien characters.
