"Gun Crazy" and *THAT* shot

Joseph H. Lewis meant to make an anonymous B-movie. Instead, he made a masterpiece.
His 1949 film noir "Gun Crazy" is an acknowledged classic -- listed among the top American films by Filmsite.org (located here) and included among the 50 most essential films in "The Rough Guide to Gangster Movies," which I have been reading religiously for days now.
Tonight I watched "Gun Crazy" and -- like the French Nouvelle Vague directors such as Jean-Luc Godard and Francois Truffaut -- I marveled at THE LONG SHOT.
Lewis placed a camera in the back seat of a car and for three minutes and 20 seconds and with one continuous shot, we seem to be passengers as stick-up couple Bart (John Dall) and Laurie (Peggy Cummins) drive to a bank, find a place to park, rob the bank and make their getaway.
It looks like we are with them!
Today, in the age of the Steadicam, such continuous shots are commonplace. Lewis' innovation was UNHEARD OF in 1949.
Lewis' long shot made the film studies' textbooks. His film lives on through the ages, because of his innovation, the acting prowess of Dall and Cummins and the great story.
