Julio who's real name is Gregory Sierra was in the movies Deep Cover & A Low Down Dirty Shame. Deep Cover starred Larry Fishburne, Jeff Goldblum, Victoria Dillard. He was a bad guy in that. I think he was a drug kingpin. Low Down Dirty Shame movie starred Keenan Ivory Wayans, Jada Pinkett, Salli Richardson, Charles Dutton. He was a captain police officer in that. He looked different in these movies cause his hair was longer & he wore glasses.

I seen him in a Low Down Dirty Shame. He also guest-starred on a episode of Fresh Prince of Bel-Air a couple of years ago.

He was also the first Lt. on Miami Vice before Edward James Olmos took over
