In which S is confused about Kurt Cobain

Recently, S and I went to the library to return a couple books. One of these was a book called "Heavier than Heaven" which has a photo of Cobain on the front of it.

S: He's going to be in a movie soon.
M: What??
S: Yeah. I saw a poster for it.
M: Umm, no, he's been dead for, like, 13 years. They are making a movie about him.
S: No, who is this? He's going to be in it.
M: THAT IS KURT COBAIN. I CAN PRETTY MUCH PROMISE HE ISN'T GOING TO BE IN IT.
S: Oh. I still think you are wrong.
