You may not have know this, but the Age of Ultron trailer wasn't supposed to be released until later this year.
The official trailer we saw was leaked onto the Internet and Marvel, instead of pulling it down, simply launched the official trailer ahead of schedule.
That's not to say that they're not pissed. Because they are.
Marvel has spent the intervening weeks since then on an international man-hunt for the leaker and rumour has it they've closed in on the leaker.
Earlier today, Marvel subpoenaed Google for IP addresses, e-mails, YouTube accounts and more.
This leak comes on the back of Expendables 3, which was leaked ahead of time and caused the film to perform poorly at the box office.
Marvel are obviously trying to nip any security leaks in the bud now before Age of Ultron's release in 2015.
