UPDATE: Marvel Granted Subpoena for Info on "Age of Ultron" Leak

Although Marvel appeared last month to take the leak of the "Avengers: Age of Ultron" trailer in stride, tweeting "Dammit, Hydra," behind the scenes the company appears determined to uncover who was behind it.

According to The Hollywood Reporter, Marvel asked a California federal judge on Tuesday to issue a subpoena to Google for more identifying information about someone using the name "John Gazelle," who uploaded "Age of Ultron" content to a Google Drive account.

While documents don't specify the nature of the file, a Digital Millennium Copyright Act takedown notice was sent by Marvel to Google on Oct. 22, the same day the trailer leaked.

Google acted quickly to remove the content, but Marvel also wants the IP address linked to the user's Google+ and YouTube accounts.

Marvel had planned to debut the trailer during the Oct. 28 episode of "Agents of S.H.I.E.L.D.," but it began appearing across the Internet six days earlier. After asking several websites to remove the footage, the company finally released the trailer itself, and instead premiered a "special look" at the sequel on Oct. 28.

Written and directed by Joss Whedon, "Avengers: Age of Ultron" arrives in theaters May 1.

Updated (9 a.m.): Deadline reports the judge has granted Marvel's request and ordered Google to bring to the court "all identifying information for the user 'John Gazelle" on Nov. 28.
