Hmm, once gain we have Red Digital Cinema claiming in their "Shot on Red" page:
Title: Captain America: The Winter Soldier
Release Date: April 04, 2014
Director(s): Anthony Russo, Joe Russo
DP: Trent Opaloch
Writer(s): Christopher Markus, Stephen McFeely (screenplay)
Starring: Chris Evans, Frank Grillo, Sebastian Stan
Genre: Action | Adventure | Sci-Fi
But then IMDB says:
Camera Arri Alexa Plus 4:3, Panavision C-, E-, G-Series, ATZ and AWZ2 Lenses Red Epic, Panavision C-, E- and G-Series Lenses
So how much was shot with Alexa and how much with the Epic?
