Jared Patrick Cox (born 6 November 1976; age 41) is an actor who appeared as a background performer in two episodes of Star Trek: Enterprise. He first portrayed an alien in a market place scene  and then a Horizon crewman in the episode "Horizon". As a background performer he received no credit for his appearances and was identified by his costume from his previous appearance which was sold off on the It's A Wrap! sale and auction on eBay. 
Cox wrote about his first Star Trek experiences on his blog. For this day he took a break from his job as a teller at Wells Fargo and went in for his make-up at 8 or 9am. He was part of a big crowd scene with over fifty SAG background performers as aliens. (X)
