Jensen Ackles revealed that he had a "horrible" time working with Jessica Alba on the 2000 series "Dark Angel." The "Supernatural" actor was brought in as a series regular on the show for its second season, which ended up being its last. Alba played a genetically enhanced super-soldier and assassin who escapes her handler and tries to uncover the secrets of her past in a near-future, somewhat apocalyptic version of America. Speaking to Michael Rosenbaum on his "Inside You" podcast earlier this week, Ackles pulled no punches in describing the negative experience he had working with Alba.
