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
