Good point Nick
I have no idea how it was with this press junket, but I remember an article from a journalist saying that some studios/producers/
pr people demand the questions before interviews and that they are only allowed to ask those. But I think everything is not yet official official. I mean Reese's involvement seemed pretty official.
I remember that Rachel got asked about her Sherlock Holmes involvement during the Morning Glory press junket, and she seemed genuinely surprised/shocked someone asked her/knew the scoop. But with the Fantastic Four rumors she also confirmed she read the script, but that one never happened.
