Liz Hurley is not really here for her acting chops (although she does get better as the movie progresses)...
What she is here for is pure titillation and she does look smoking in a variety of outfits, intended to illustrate the wicked temptation of the devil in disguise. There is a moral lesson in here somewhere, but I forgot to pay attention. There are some nice comedic touches - using the office mates as accompanying players in all the 'fantasies' and there were some good visual gags throughout. Nothing groundbreaking here though.
If you're looking for a consistent and brilliantly acted film- this also is not it.
What this is- is hilarious. It's stupid, ridiculous & points out, in the most simplistic of ways, that even if you have everything you could possibly want in the world- all of the riches, the notoriety, fame- the best way to be successful and truly happy is to be yourself, as you come. There's something oddly warming about that notion which is beautifully clad in crappy slapstick humour, tongue-in-cheek innuendos and Liz Hurley's there-but-not-really outfits.
