One of my students did his graduation thesis on the Titanic disaster, considered as a vehicle for presenting dramatic fiction.I have four Titanic films and all of them are different. I also have three film versions of Melville's Moby Dick
and all of them deviate in interesting respects from what Melville actually wrote. With a film like Troy
, you have a double issue, for the film in which Brad Pitt plays Achilles has been criticized from deviating from Homer's account of the Trojan war, but his account is highly fictional to begin with.
