Movie/game tune duets for grade 5 standard players

Hello everyone,

My fiancé and I are both long time flute players who both reached grade 5/grade 6 standard and are looking for duets we can play together, the majority of what we can find in the shops seems to be flute + another instrument. We love listening to movie and game theme tunes but are open to any other suggestions. If you can think of anything that you would recommend please let me know.
