The Cross series from James Patterson has been a mainstay on bestseller lists. The eighteen books have been massively popular but have warranted fewer movies than you would think. Along Came a Spider and Kiss the Girls were popular ‘90s films, and Tyler Perry is finally bringing the intense detective back to life with Alex Cross. Rated PG-13, this movie looks to be as intense as the books, but with Tyler Perry starring will certainly carry a positive message with it.
