Avengers: Age of Ultron is only three weekends away from release, and the anticipation is growing at a fever pitch. Helping to keep fans satiated is a brand new extended TV trailer that features some select new footage. Most of it revolves around Scarlett Johansson as Black Widow. This latest sneak peek runs 90 seconds, and serves as a roll call for the world's greatest heroes.

The epic follow-up to the biggest super hero movie of all time, Avengers: Age of Ultron begins when Tony Stark tries to jumpstart a dormant peacekeeping program, things go awry and Earth's Mightiest Heroes, including Iron Man, Captain America, Thor, The Incredible Hulk, Black Widow and Hawkeye, are put to the ultimate test as the fate of the planet hangs in the balance. As the villainous Ultron emerges, it is up to The Avengers to stop him from enacting his terrible plans, and soon uneasy alliances and unexpected action pave the way for an epic and unique global adventure.

While this is an extended look at a TV spot released last week, it does offer up some exciting new action. The spotlight here is on Natasha Romanoff. While we've seen Captatin America lose his shield before while fighting Ultron on top of a moving vehicle, this gives us more from the chase sequence, as Black Widow retrieves the shield, showing her stunt prowess on the new Harley Davidson motorcycle she rides throughout the film. She truly is the boss, coming to everyone's rescue at the last moment. Take a look:
