To solve the second one, you had to think about where Giant Eagles might be mentioned. The first thing that comes to mind is The Lord of the Rings. Then, you had to somehow connect this movie to one of the profiles.
To solve the third one, you just had to do a little Googling about D&D, and you would have come across the words Forgotten Realms.
Well, I won't argue, the clues were completely beyond me.
