So, in pairs Kevin Costner and Christine Baumgartner, as well as George Clooney and Amal Alamuddin, men are 17-20 years older. There are examples with an even greater difference, 25-30 years old - these include Jeff Goldblum and Emily Livingston, as well as Dennis Quaid and Santa Auzina. In some couples, the age difference was very large.
