Captain America: The Winter Soldier will be released this weekend and Marvel already has set a release date Captain America 3. The third installment is set for May 6th, 2016 which will take place post-Avengers: Age of Ultron. Marvel has brought back the Russo brothers to director and are working the screenwriters on the script. Franchise writers Stephen McFeely and Christopher Markus are also back.
It's crazy to think the third movie will actually be fifth Marvel movie with Steve Rogers. While it's hard to predict what is going to happen in the next film, we've had a few hints what could be in it. Of course, a lot of this could change in the next two years, but here's what we have so far. An easy assumption to make is that Sam Wilson (Anthony Mackie), Black Widow (Scarlett Johansson), Sharon Carter (Emily VanCamp) and others will be returning.
VILLAINS: Thomas Kretschmann who plays Baron Wolfgang von Strucker, has confirmed there is future for his character within the MCU (post-Age of Ultron). This makes perfect sense as Strucker is the face of the modern-day version of HYDRA and could be the type of standout main villain the franchise needs. Baron Zemo has also been teased in Winter Soldier concept artwork (one of their off-screen WWII missions was titled "Operation: Zemo"), and at one time both were in early drafts of The First Avenger script.
Crossbones is expected to make a return, depending on the outcome of Winter Soldier. We've heard that Drew Pearce is considering making a Crossbones and Sin Marvel One-Shot. Sin just happens to be the daughter of The Red Skull and is the villainous partner of Crossbones. She eventually takes the place of her father as the new Red Skull. If Marvel decides bringing back the original Red Skrull might be too difficult to explain, this might be their second option.
While speaking with BadassDigest franchise writers Stephen McFeely and Christopher Markus gave hints to where the third film could be going and reveal that another Ed Brubaker storyline might be used. Christopher Markus hinted at "psychotic '50s Captain America". William Burnside is so obsessed with Captain America he changes his name to Steve Rogers, gets plastic surgery and takes an untested "super-soldier serum". His story was recently explored in Ed Brubaker's run of Captain America and would see the mentally-damaged would-be hero exploited similar to how the Winter Solider, eventually becoming a villain known as The Grand Director (a version of the villain brainwashes Sharon Carter). I wouldn't be shocked if Bucky's puppet-masters end up making a return, or perhaps Strucker and HYDRA are involved. While it's an interesting concept the writers are known for giving false information, previously teasing Modok for the second Captain America film.
