I found a couple of fan-made Imperial Agent tribute videos or trailers, both featuring the female Agent. This one is really good and covers the start of Dromund Kaas. There are minor spoilers for that part of the story.
This one, by the same author, covers the prologue in Hutta. It does spoil the twist in the Hutta storyline, though, so you may want to avoid it if you're planning on playing an Agent in the near future.
