I think banter between an actor and director, (playful or otherwise) far removed from the set of the film goes a bit beyond the realm of critique and discussion of the actual film here.
Some fans are so eager now to paint RJ as this horrible monster who took a steamer on Star Wars, they will latch onto anything to support that argument. I fully expect RJ to be accused of indirectly causing Carrie Fisher’s death if this keeps up. 😕
Rian and Carrie really got along well. I wish she was here so she could let loose on the complainers.
