The biggest disaster that could ever befall Hollywood is The Rock leaving. The 2nd biggest would be an earthquake that killed everybody.Dwayne "The Rock" Johnson stars in a by-the-book disaster movie. California experiences a huge earthquake, a nerdy scientist predicts it but not in time, and The Rock has to save his family. Sure, he lets tons of people die in the mean time, but he's really into his family.It's not great, and it's certainly not The Rock's most The Rocking movie, but it's got plenty of fun stuff and the CG destruction of many parts of California that kinda deserve it.
