Every episode reminds you that the dialogue is well, pretty much fact - but I have a hard time not believing the show took extreme liberties with the facts. That said, I definitely enjoyed the series very much. It's one of those, "OK just one more...OK just one more then I'm going to bed. OK just one more..." things that keeps you up too late. Donald Sutherland is GREAT as J. Paul Getty and even resembles the original JPG. I'm going to give Donald a .362 score as related in baseball batting averages for the entire season. The next heavy hitter is Brendan Fraser as the likable Fletcher Chace, with a BA of .340 and a lot of dingers. Luca Marinelli as Primo is a SOLID 3rd baseman with a strong arm hitting .309 with zeero errors. Fine actor. Silas Carson as the butler is impeccable, a .325 hitter and an errorless season. Harris Dickinenson as JPG III was a touted first round pick but ended up hitting .234 with too many strikeouts.
Much of the show takes place in Italy, where they speak Italian - so I read what they were saying. I'd say the whole Italian cast did a fantastic job, most outstanding - Primo - see above.
Beautifully filmed, most scenes take place at The Mansion or in Italy. Watch it, you will like.
