Question: Can someone please tell me why Kurt Russell is playing his own father in the flashback scenes. I just don't understand why.

Gavin Jackson

Chosen answer: Why not? There's no reason why an actor couldn't play his own father at the same age - indeed, it can serve to emphasise a family resemblence between father and son. It can also serve as a swift way of letting the audience know that this is the father, rather than having a different actor come in and have to have the relationship established through dialogue.
