I've been to the Heiress stage door twice. Very few of the cast members come out the stage door -- maybe 3 other people besides Chastain and Stevens. I did not see Strathairn or Ivey either time.
The barricades themselves are extremely short, so the crowd is fairly deep. Stevens signs for everyone within reach, but not everyone is within reach. He is very nice, although there is a some fan hyperventilating with him. He seemed to take it in stride, though.
Both times I went, Chastain had visitors, and didn't come out for 45 minutes or more. But when she came out, she spent a lot of time taking photos, talking, and signing for everyone. She is also very nice at the stage door, and pretty dedicated. I went the night before the Golden Globes, and she signed until close to midnight, taking her time and not rushing at all. Then she said she was going directly to the airport to catch a flight to LA for the Golden Globes. A lot of actors would have been more rushed about it, or bailed completely.
In addition to winning so many awards recently, she also was the top-billed actor in both of the top 2 movies at the box office this weekend. I think that was the first time that has happened since Leonardo DiCaprio did it with Titanic and The Man in the Iron Mask back in 1997. This is really her time.
