Just noticed an error in #8 ('lose one' snuck in there), so here's the password again with it corrected.
1. - A chocolate frog? O but Ed, no! He is no lord!
ARWEN - Turn round and restore the sun god in the evening.
3. - Singer of Middle-earth's GREATEST songs left his signature underground.
ELESSAR - Half-resist the sale, mix it up with many titles.
5. - On the radio, the next word: Aiya Eärendil Elenion Ancalima!
FIRE - One thing the movie archers did not do; it's pretty hot.
7. - A French element in the belly of a ship; instead of the end, a hole (and French swapped and moved) - wear a mask here!
8. - Um (not um)... look back, briefly see the Sea, and it's lonesome.
9. - A space station! Quick, it's okay, it's just a tree (but it's dark...)
10. - As it took the Fifth, it roared.
For #3: how could you write Tom Bom's signature in a way that gives an undergroundy word?
For #1: the straight clue is a direct textual reference, not anything oblique.
And I will admit that the 'French element' in #7 is a chemist's joke.
