"Mad Men" actress January Jones and rock and roll royalty Zoe Kravitz have both joined Matthew Vaughn's X-Men: First Class, reports Deadline.com. The two board a cast that literally grows larger by the day - yesterday we wrote about Oliver Platt and Jason Flemyng joining up, and the day before that we touted the Rose Byrne announcement. At the moment, there are approximately 3,259 actors in the film, and there's no sign of letting up...

Riley Keough, perhaps better known as Lisa Marie Presley's daughter and the granddaughter of Elvis Presley, has been tapped to co-star alongside Tom Hardy and Charlize Theron in George Miller's Mad Max: Fury Road (aka Mad Max 4).

The actress is still "in talks" for the role; Keough would play one of the "Five Wives", a group of women that Mad Max (Hardy, Inception) is protecting. Teresa Palmer, Adelaide Clemens and Zoe Kravitz play three of the other wives. (Kravitz herself is the daughter of musician Lenny Kravitz.)
