Morgan Freeman was the actor who played the original Alex Cross
I love all the Lee Child novels and was also very disappointed in TC as the choice for Jack Reacher. Reacher's height and bulk are mentioned in everyone of the books and are integral to the story. It is what sets Reacher apart...and makes him noticeable i.e. gets him involved. TC at 5'6" is a shrimp in comparison LOL
As for "My sister's keeper", the movie was okay but the book is ten times better. And yes, they change the ending in the movie so book and movie do not end the same. Hated that!!
