POSSIBLY! Today's Finnick rumor is brought to you by once again, laineygossip.com who claims:
I’m told that Hedlund auditioned for the part of Finnick in Catching Fire
for director Francis Lawrence about 10 days ago. It went very well. No
final decisions yet but interest in Armie Hammer seems to have waned
since Hammer wasn’t as enthusiastic about it as Lawrence was about him.
Am told they’re still seeing people. But their priority right now isn’t
so much casting as it is about getting the script in better shape.
Very interesting to hear, as ten days ago would put all this "frontrunner" hubbub around the exact same time as Garret allegedly auditioned. Remember folks, this is all heresay. Nothing will be confirmed until the Finnick casting is announced.
