First of all please don't be put off by the fact The Rat Pack is a television movie it's fantastic.
The film looks at the heyday of the Rat Pack in the early sixties when Frank Sinatra, Dean Martin, Sammy Davis Junior, Peter Lawford and Joey Bishop were the coolest guy's in the World with Movies, Music, Fame and Girl's all at their finger tips.
Based around true life events we see the members of the gang get mixed up with JFK, The Mafia and far more in between.
Ray Liotta (Goodfellas) plays Sinatra as a sensitive and volatile character. Joe Mantegna (Fat Tony in The Simpsons)shines as Dean Martin with an uncanny impression. Don Cheadle (Oceans Eleven) plays Sammy Davis Junior and although he doesn't look like Sammy he gets his character and impression just right.
If you like the Music of The Rat Pack or enjoy a good Drama then The Rat Pack is worth watching.
