David Boreanaz: Then
The brooding heartthrob was actually discovered by a talent agent while he was walking his dog. The agent realized Boreanaz would be perfect for Buffy's vampire lover. As one of the few vampires with a soul, Angel led a complex existence, and eventually left Buffy at the end of season 3, though he made several appearances in the later seasons.
