7. Emma Watson & Natalie Portman
Two of Hollywood's most well-known female actresses (and generally regarded as two of the most adorable ones) have a bit of an age difference that could make up for some great drama.
The Logline: Basically, a sequel to
Leon: The Professional that finds Portman's Mathilda now an expert assassin who is met by Watson and informed that she is her long, lost sister. Together, the two take down a mafia crime lord whose entire chain of employ are just different interpretations of Nicolas Cage.
Directed by: Luc Besson
