I am attending D23 Expo this year. My husband is a huge fan of a few movie stars that MAY show up this year, namely Christopher Eggleston, Tom Hiddleston and Idris Alba (THOR) and Rita Wilson (SAVING MR BANKS). If these stars do show up in the D23 Arena, what do you think my chances are of getting an autograph for my husband?

Has anyone ever gotten an autograph from the movie stars that show up at the D23 Arena? Are there ever signing sessions afterward?

I have heard about the AVENGERS cast and PIRATES cast at the prior D23 Expos. Did anyone ever get anything signed from those actors?

Thanks!!
