Brian De Palma's second highest entry on this list, The Untouchables, is a searingly good adventure through prohibition-torn Chicago. Many stand-out moments (with the exception of Connery's supposedly Irish accent) make this film a classic with a fantastic cast. Robert De Niro plays chubby Al Capone and threatens (as usual) to steal the whole show with his relatively brief screen time. The score to this film also boasts the second best in an incredibly long and great career from legendary composer Ennio Morricone, second only to his iconic work on The Good, the Bad and the Ugly. Iconic Moment: After the death of Jim Malone (Sean Connery) at the hands of a Capone goon, Eliot Ness (Kevin Costner) arrives to hear his last breath and also just in time to be told of the train that Capone's accountant is set to leave on. The set up is there for Eliot and his remaining partner George Stone (Andy Garcia) to make there way to Union station in order to apprehend the accountant and take him alive so he can testify against Capone. Cue the wonderfully devised shoot-out in Union Station a complete homage to 1925 Russian film Battleship Potemkin and its famous Odessa steps scene - where Ness and Stone finally get the man needed for court.
