Their Last Film
The rat pack had multiple films together. Dean Martin, Sammy Davis Jr., and Frank Sinatra all starred in Cannonball II together. It was the last time any of the rat pack members worked together in a film.
Jail Time
A young, 23-year-old Frank Sinatra was arrested for sleeping with a married woman. In 1938, Sinatra was caught in bed with a woman wearing a wedding ring. At the time, this was a felony in New Jersey. The charges were dismissed quickly, but this was definitely a life lesson for the young singer.
