Please, I didn’t see anything.
In a flashback, Winter Soldier is shown taking out a number of Russian men in a hotel, but also killing an innocent man that accidentally witnessed the assassination.
The Živnobanka Palace in Prague, which has amazing architecture, stood in for this hotel. Thanks to geektrippers for the assist on this location.
