"Do not speak to me of dragon fire"

The scene in question seems to have the Elves pointlessly hanging around just out of sight of the gate of Erebor; they pop up, Thorin sees them and asks them to help, and then they go away again. Why were they there in the first place? Perhaps in the films it's a big conspiracy and they knew Smaug was going to attack the whole time!

In actual fact it might have something to do with an idea in the films (which is apparently expanded on in the Extended Edition) that Thranduil used to go and do homage to Thrór because he was the most powerful ruler in that part of the world (while resenting doing so and secretly coveting his treasures) and perhaps he was on his way to some kind of political visit to Erebor when he saw Smaug attacking and decided "let them burn" as it were. That's an awful lot of film embellishment coupled with interpolation on my part though.

It's also possible that he was on his way to attack the mountain to recover those jewels he covets from the novel, which are embellished in the films to have belonged to the wife who was killed by dragons (which gave him the scar which was part of the original point of the thread). That's another thing that only exists in the filmmakers' heads, however.

Either way, it doesn't look like he and his Elves were en route; it looks like they were just waiting around for no reason, an example of the clumsiness in the visual language of the films that is very common.

In the rest of the films, Mirkwood is still several days' march from the Mountain as it is in the book.
