Have you ever read The Alchemist?
No I haven't! Who is the author?
It's a great book by Paulo Coelho 
Has Paulo Coelho written any other books you would recommend me to read?
Yes he has written tons of other books, but another one I recommend is Brida
I will try Brida, thank you! Do you think there will  be a movie adaptation of the Alchemist any time soon?
I have no idea! But I think it would be great if it was done right. The book is sort of a coming of age story, so i think it would take the right cast to pull it off 
Who would you like to see in the movie?
Hmm, I can't think of anyone off the top of my head
Idris Elba is one of my favourite actors, would he be good?
