on the accuracy part, a lot of reviews from magazine and newspaper articles usually had the same phrase that, "in the movie are things Orson wouldn't have done or said."
if you like a movie about wars, citizen kane and the so called subject, would be the ones to watch.
if you want to see a damned good movie, forget citizen kane, and find the other movies Mr. Welles has done. like chimes at midnight, and others. then let me know where i can get them.
don't take my 'forget citizen kane' that seriously. if you've seen it as many times i have, you know it by heart, and are ready to see the others too.
