'Captain America 2' continues to film in Cleveland, but up until this point we haven't seen anything of the titular character, The Winter Soldier. That all changes today as the Marvel sequel films a big action sequence on the streets of Cleveland and reveals the return of Bucky Barnes.

Despite a rather hilarious sign from a production assistant pleading, "NO PICTURES PLEASE!," plenty of pictures were taken on the 'Captain America 2' set this week of actor Sebastian Stan in his Winter Soldier get up. At first glance, it's hard to get a glimpse of his robotic arm (though you can see his metal hand through the glove), but you can see the longer hair and leather jacket that matches the look of comic character. As for the eye mask, Marvel wisely ditched the Lone Ranger look for a mask that covers almost the entirety of Stan's face. It looks...a little strange (not unlike Joseph Gordon-Levitt's Cobra Commander from the 'G.I. Joe' movie), but hopefully this is something that will be explained in the movie.

The scene being filmed was reportedly a chase sequence that ends with the black SUV, seen below, exploding. We'll assume that the Winter Soldier is behind that.

'Captain America: The Winter Soldier' follows the modern-day exploits of Steve Rogers as he, Black Widow and Nick Fury team to "battle a powerful yet shadowy enemy in present-day Washington, D.C." One of those enemies is the Winter Soldier, Cap's former sidekick Bucky Barnes, who was built into a supersoldier in his own right and is now an assassin working for the government.

'Captain America 2' hits theaters on April 4, 2014.
