Continuity mistake: When Yelena Belova is found by the survivor scientist in Malaysia, she advances towards him, hands raised. However, she holds the explosive in her right hand in different ways between shots (check when she mentions the "breakthrough").
Plot hole: How did Red Guardian drive from Washington, DC to Utah, a distance of more than 2,000 miles, in a limo that can't seem to go more than about 54 mph?
Continuity mistake: Rep. Bucky Barnes is stopped by reporters on his way to the hearing of Valentina Allegra de Fontaine. One reporter asks him a question; Bucky responds in a less than impressive fashion and then walks off. The reporter turns her head as he walks past her, but in the next shot, she is staring into space in front of her, and only then turns towards him again.
Continuity mistake: The Thunderbolts are confronting Valentina Allegra de Fontaine at the Avengers Tower. She makes her entrance, champagne glass in hand. The position of her left hand changes throughout the scene a few times between shots—in particular when she addresses Bucky's "less than half a term" at the beginning and when she speaks with Red Guardian.
