Note: The following is an excerpt from Variety October 14, 2013 –
“Whomever the studio and producers Michael de Luca and Dana Brunetti decide on, the process will involve testing with Dakota Johnson to make sure the chemistry is right and that could take weeks, leading the studio to go the new, discovery route since most established actors aren’t looking to waste their time reading for roles.”
