Yes, this is the movie Kevin Spacey was removed from and replaced by Christopher Plummer. Unfortunately, that is what this film is destined to be remembered for. In case you've been living under a rock, in the wake of Kevin Spacey's disgrace from multiple sexual misconduct allegations, director Ridley Scott and Sony decided to refilm every scene of this film with Spacey in it, with Plummer in his stead. This reportedly cost $10M and put the film in danger of not making its original planned 12/22 release. Well, they did it and they made it (or at least just 3 days later than originally planned). The good news is, if you didn't know all this, you wouldn't notice anything different or peculiar about the film. It looks like Plummer was in it all along. I certainly didn't notice any scenes that looked awkward or didn't match. So, don't go see it because of all the drama. Go see it because it's a really interesting film about J Paul Getty, the world's first billionaire, and the kidnapping of his grandson. It's an interesting and entertaining watch.
Who is this movie for? If you're not worn out already by all the Oscar bait prestige films we've been inundated by, this is another good one. You can go back to action blockbusters next year.
