Following last week's first peek at Sebastian Stan as Winter Soldier on the set of Captain America: The Winter Soldier, we now get a look at the character in action -- complete with his bionic arm.

The photos arrive courtesy of Ain't It Cool News, Comic Book Movie, and Cleveland's Plain Dealer, which after having its city transformed into New York City and Stuttgart, Germany, for 2012's The Avengers, has become quite adept at chronicling the ins and outs of movie production.

Directed by brothers Anthony and Joe Russo, Captain America: The Winter Soldier also stars Chris Evans, Toby Jones, Cobie Smulders, Samuel L. Jackson, Scarlett Johansson, Anthony Mackie, Emily VanCamp, Frank Grillo, Max Hernandez and Robert Redford. It opens April 4, 2014.
