well with all the cross references the director threw in animals for god's sake i wouldn't be surprised by how many easter eggs were in it also for citations being online or not it's not always possible to find a link books are referenced but these books are highly unlikely to be available online if they are probably copyright violations of course an attempt should be made to fetch a link but sometimes these things are subscription only or just aren't online especially older sources i haven't seen the film so i'll probably have to check it out on dvd it's not so bad to work on the film article without having seen it though talk contrib review
