When Marvel announced that Thor: The Dark World will be released on Blu-ray 3D, Blu-ray and DVD, it was revealed that one of the special features will be an exclusive first look at Captain America: The Winter Soldier. Today, a Tumblr user has posted the three-minute video with new footage from this Marvel Phase Two adventure, arriving in theaters April 4. We also get interviews with producer Kevin Feige, who reveals new information about Robert Redford's Alexander Pierce, while Chris Evans talks about his former friend Bucky Barnes (Sebastian Stan), and how he was turned into the Winter Soldier. We also hear from directors Anthony Russo and Joe Russo, Chris Evans, Samuel L. Jackson, Robert Redford, Scarlett Johansson, Sebastian Stan and Anthony Mackie. Check out the new footage, along with a new photo of Scarlett Johansson as Black Widow, then read on for Easter eggs already discovered in the impending sequel.

Sharp-eyed fans have spotted cool little Easter eggs in both a new photo and Sunday's trailer for Captain America: The Winter Soldier. Yesterday, Marvel released eight new images from the sequel, one of which featured Chris Evans and Scarlett Johansson. At first glance, it looked to be just another normal, almost boring look at the movie. However, upon closer inspection, Scarlett Johansson's Black Widow is wearing something that fans of Hawkeye (Jeremy Renner) (from Marvel's The Avengers) will surely enjoy. An arrow necklace...

2012's Marvel's The Avengers seemed to plant the seeds for a romance between Black Widow and Hawkeye, and this arrow-shaped necklace may indicate that their relationship has been taken to a whole new level, although that's purely speculation at this point. Especially since something seems to be brewing between Steve Rogers and Natasha Romanoff in all of the trailers and footage we've seen thus far. Is a love triangle in the works?

Another eagle-eyed fan noticed that, in Sunday's trailer, there was a very special cameo that most viewers missed. Comic book legend Ed Brubaker, who created The Winter Soldier character and wrote the comic book story upon which this sequel is based, was spotted in the opening moments of this new footage, as a technician who is attending to The Winter Soldier. ComicBook.com posted the image below, after first seeing it as the background of Ed Brubaker's Twitter page.
