I feel a bit conflicted about this one. Author Carrie Fisher discovered some old diaries she kept during the filming of Stars Wars for 3 months in London, in 1976. The book however is not really an insight into the movie, but more about how she felt and was affected by a relationship with co-star Harrison Ford.
She does however not give a lot away, still being a bit discreet. There are a lot of diary entries regarding her insecurities and a lot of poetry. I did find parts of it a bit confusing as stories sometimes seemed a bit untold. 3/5
