I just started reading it yesterday, September 13, 2019. I had not noticed that it was written by Richard Lagravanese who directed one of my favorite movie, "P.S. I Love You..
So far Jeff Bridges' character Jack Lucas is even meaner than in the film.
Before I go further, I loved that movie. This was Robin Williams at his best and in there you could see he could do drama just as well as comedy but nobody seemed to want to give him a chance. His more serious movies if they did not include a bit of comedy like What Dreams May Come or The Dead Poet Society or Patch, people seemed reluctant to watch them. I did. Robin was wonderful in Insomnia with Pacino and Swanks. He gave me the shivers. He was a great actor and to this day I'm still in shock that this beautiful human being should have suffered so much as to take his own life. I blame the person who lived with him as she should have seen the signs.
I'm on the page where Jack is egging on one regular he loves to torture and as it turns out for whoever read the book or saw the film, that character will play a big part in changing Jack's life and that of Perry too.
Basically the book is a faithful rendition of the movie and both are good. I loved that movie. Robin Williams starts as a loving adorable funny bum called Parry but when you find out more about him, you find out how he became Parry and it is tragic in some way. He used to be Henry Sagan, professor of medieval history, happily married to the beautiful Elizabeth. There is a reason Jack Lucas played by Jeff Bridges becomes intertwined with Parry. In some way, some of the actions of Jack are responsible for Parry's condition and tragedy. Once Jack learns that he sets out to try and help Parry find happiness again with Leticia Sinclair marvelously played by Amanda Plummer. I loved Mercedes Ruehl's Anna Napolitano. In reality a man like Jack Lucas if he got back his posh life, fame and the hot model girlfriend might never learn it that he is actually meant to be with Anna but hey, it's fiction. You need to have a pure heart like Parry to see beauty in somebody plain like Leticia and Jack doesn't have that.
