The 'Resident Evil' video game franchise is one of the most successful of all-time, selling over 61 million units since the first game made its debut on the Sony PlayStation in 1996. The game series was so popular it spawned an equally lucrative film franchise, which includes five movies (and a sixth on the way) that have grossed almost $1 billion worldwide. But, would all that have happened if Gwyneth Paltrow had starred in the movie? Because that almost happened. Find out more about that, and other scary scoop from the 'Resident Evil' movies is this week's horrifying You Think You Know Movies? episode!
