Update May 1: Paramount is out with a another version of the first Teenage Mutant Ninja Turtles trailer. It's hard to call it a new trailer because it's the same as the last one just 10 seconds longer, but that 10 seconds is exclusively new footage of the Turtles in action.
Go straight to the 1:00 mark if you want to just see the new footage.
Update: And since that footage hit, it appears Paramount decided not to wait to release the full teaser trailer. Here's the one and a half minute spot in HD, with full, close looks at Leonardo, Donatello, Michaelangelo, and Raphael - as well as at least the mask of Shredder, who, when he attacks, we fully expect these turtle boys will cut no slack.
Original Story: The first footage from Teenage Mutant Ninja Turtles, the Michael Bay/Paramount reboot feature film, has hit the internet Thursday morning, after airing on The Today Show on NBC earlier in the day. The footage, at least for now, captured by JoBlo.com is grainy and low-quality, but we'd be shocked not to see a higher quality version show up later in the day, and will update as it comes.
This is the same footage Paramount debuted at CinemaCon earlier this week. The company has announced the trailer for the film will debut with Captain America: The Winter Soldier. Teenage Mutant Ninja Turtles is due out August 8, 2014, just one week after Marvel Studios debuts Guardians of the Galaxy.
