Jack Rollins is a supporting antagonist of the 2014 Marvel film Captain America: The Winter Soldier. He is a STRIKE member who is the right-hand man of Brock Rumlow and a fellow HYDRA agent working for Alexander Pierce.
He was portrayed by Callan Mulvey.
Rollins first appeared when he was sent alongside Captain America, Rumlow, and Black Widow to help a ship called the Lemurian Star hijacked by pirates (led by Georges Batroc). To that end, Rumlow and Rollins blew up a door after Captain America took down most of Batroc's men, allowing the two to free the hostages (including Jasper Sitwell).
However, Captain America soon learned that Batroc was hired by S.H.I.E.L.D. director Nick Fury to uncover the true intention of a project called Project Insight, which involves utilizing S.H.I.E.L.D.'s weapon and an algorithm (developed by Arnim Zola) to create a new HYDRA world order. It also turns out that Rollins is involved in the plot, as he and Rumlow are assigned to capture Captain America after the latter suspects of Pierce being the true mastermind behind the plot.
As Captain America is on the run, Rollins is tasked to take him down at all costs, as well as standing guard when Pierce utilizes a brainwashing machine to manipulate the Winter Soldier into doing HYDRA's bidding. Eventually, in the end, Captain America revealed to all S.H.I.E.L.D. agents the truth about Project Insight and HYDRA, so Pierce orders Rollins and several STRIKE soldiers to take all of the World Security Council members hostages. However, one of the members appeared to be Black Widow in disguise, and she took down Rollins and his men with ease before Fury shuts down the project and shoots Pierce to his death.
It can be implied that Rollins, along with his surviving conspirators, is arrested and sent to prison afterward.
