Marilyn Monroe & Arthur Miller
While playwright Arthur Miller and pop culture icon Marilyn Monroe were not together for much of the 1960s, it is fair to say that anything involving the actress warrants mentioning. They were married in 1957 and stayed together into the first few years of the 1960s.

However, they got a lot of media attention since people thought their pairing was very mismatched. Sadly, this power couple decided to split while working on the movie The Misfits together. Miller wanted to write a movie that allowed Marilyn to be considered a serious actress, but Marilyn disliked the script.
