Comment: IMDB.com lists Tonantzin Carmelo fourth and Michael Spears fifth in the credits. But if you go by the trailer, their roles seem relatively minor. The trailer shows Carmelo a couple times and that's it.
I must say I'm not impressed with this trailer. After watching it, I'm not sure what Shadowheart is about or who the main characters are. Nor does it seem like a tense, gripping story. I'd suggest making another trailer with fewer slogans (e.g., "revenge or redemption") and more narrative.
