He did end up winning two oscars for best director and these films also won best picture. He was also nominated for best actor twice. HIs earlier career stuff was ignored byh the academy bedcause they weren't the "oscar type" of films that generally got nominated then, but later in his career the academy had expanded the type of films that got oscars, so he started winning. According to wiikipedia he was nominated 11 times for oscars and he won 4 times, and they are including best picture awards for films that he directed. I do not recall any scenes in his films during which he farted, but I haven't seen all of his movies either. He may also have farted silently, the most sneaky kind of farting.
