Tropes that apply to Theo Rossi's roles:
- Anti-Hero: He tends to play sympathetic criminals a lot.
- Butt-Monkey: His two most famous roles both see his character undergo a Trauma Conga Line.
- Plays Great Ethnics: He's of Italian, Spanish, Syrian, and North African descent, so he plays characters of diverse backgrounds, mostly Latino or Italian. This is particularly exploited in Sons of Anarchy, where he plays a mixed-race biker passing as a Latino. In Emily the Criminal, he plays a Lebanese man.
