On this week's episode of Marvel Entertainment's The Watcher, host Lorraine Cink spoke with Avengers: Age of Ultron director Joss Whedon on the casting of James Spader as Ultron in the film, marking the first time he's spoken publicly about it since Spader was announced (although, interestingly, he's commented before this on Batfleck).
"Spader was my first and only choice," Whedon told the show. "He's got that hypnotic voice that can be eerily calm and compelling but he's also very human and humorous. Ultron is not HAL. Spader can play all of the levels."
