Marvel So, when Sebastian Stan swung by The Tonight Show Starring Jimmy Fallon, he opened up about how the movie was kept a secret from the cast, too. NBC Basically, the cast didn't know the context of their scenes until they arrived on set. NBC Sebastian said one scene in particular that was kept a secret was the fact that everyone was gathering for Tony's funeral. Marvel He said that the cast was told that they were filming a wedding by a lake and his costume consisted of nice attire. NBC On the day of filming, he arrived and found out who was in the scene...and who wasn't.
