The Captain America: The First Avenger shoot continues to provide small glimpses into one of the most highly-anticipated films of 2011.

A week ago we posted the first images of Chris Evans as Steve Rogers. Today, we’re giving you a look at a sleek-looking submarine prop, presumably of HYDRA manufacture, as well as new video and images from the aforementioned Manchester shoot with Chris Evans.

The submarine images come courtesy of The Liverpool Daily Post, who report that local port, Stanley Dock (which is on the River Mersey) has been a hotbed for fan speculation – some believed filmmakers were even building a full-scale German U-Boat. Speculation aside, Joe Johnston and his team have made some cosmetic alterations to the area, creating a 1940s era New York set – with a few fictional Marvel Universe embellishments.

While currently unconfirmed, it’s not a stretch to assume the newly revealed submarine belongs to the fictional terrorist organization, HYDRA. Not only does it lack the kind of patriotic flare we’d expect from a Captain America vehicle (which normally feature a red, white, and blue color palette – or at least the iconic Captain America star) but the design also matches up nicely with the HYDRA motorcycles we saw a few weeks back.

Check out the images of the HYDRA submarine below:

In addition, we’ve got new photos and video from last week’s Steve Rogers on the go shoot featuring an extremely buff Chris Evans running in prosthetic feet.

The video is a fun glimpse into production and the images offer a few new details on the events that unfold in the scene – including Evans’ stunt double tackling a gun-toting stunt woman.

Check out the set video and images below:

What do you think of the design of the HYDRA vehicles we’ve seen so far? What else would you like to see make the jump from the pages of the Captain America comic books to the big screen?

Chris Evans stars alongside Neal McDonough’s Dum Dum Dugan, Tommy Lee Jones,Hugo Weaving as the Red Skull, Hayley Atwell as Peggy Carter, Dominic Cooper as Howard Stark, and Sebastian Stan as Bucky Barnes. Captain America is of course, directed by Joe Johnston.
