It occurred to me recently, having re-watched Star Wars Episode IV: A New Hope, that I didn't notice any occurences of the Force being used to physically manipulate anything throughout the movie. Obi-Wan uses the Jedi mind trick on a few occassions, and Luke uses the Force as an alternative to his targeting computer, but I don't recall them lifting or throwing anything.
To that, the first instance I can think of where the Force physically interacts with anything is in the opening of Star Wars Episode V: The Empire Strikes Back when Luke retrieves his lightsaber.
Was there some instance of the Force being used to physically manipulate something in A New Hope that I am missing? Or, if not, was there always the idea that the Force could physically manipulate something during the production of A New Hope?
