Wow! Danny Trejo! I LOVE him! He's usually portrays the second bad guy to the left, but he's excellent.
Danny Trejo's credit list is vast, but his performances I've enjoyed the most are: Navajas in Desperado, Spider-Man in The X-Files "Redrum," Spyder Rudner on Monk's "Mr. Monk Goes to Jail," and Cucuy in Once Upon a Time in Mexico.
