In an interview with Metro on Saturday, McFeely talked about having stars Chris Evans and Scarlett Johansson help out on the screenplay for Winter Solider.

"The script was in pretty good shape when we started, but Chris had a lot of input on the scene where he's meeting Sam Wilson for the first time," McFeely said "And what it would take to make Captain America - who probably gets stopped in the street all the time - turn around for that extra conversation."

He added that both actors are a lot of help when it comes to developing scenes. "(Evans) and Scarlett were involved in that scene in the car when they're driving to Camp Lehigh and they're talking about kissing and all that," McFeely said.

"I think actors very often know their voices better than I do, so I have no problem with them adding a couple of lines to a scene or telling a different joke. It's only when they want to take a scene and make it about something else that it gets problematic. As long as we get what we're trying to accomplish then I don't care."

As for the plot of Captain America 3, McFeely said that he wasn't too serious about going into the 1950s psychotic Cap plot line. "That was a joke!'

Captain America 3 is set to open in theaters on May 6, 2016.
