Favourite Films: One Hour Photo

Robin Williams playing a simple delusional lonely man. In many ways this film is too sad to watch. Excruciatingly embarassing but fascinating at the same time.
The main character is a nice man at heart, but so lonely he latches onto a family he absolutely no connection with, beyond that he develops their photos at the local mall. A relatively low skilled job he probably mastered in a few months.
What makes this film work so well is:
1) The insight it gives into how a basically good man, can become so delusional and lonely. Later under duress he is driven to a terrible mistake.
2) The film is beautifully shot, the sad character is always in stark light, which hardens the poverty of his existence. While the "ideal family" with a fantastic home and all things beautiful are shot in rich colours ...
3) A good sound track - atmospheric and perfectly fitting the mood of the film
4) There is a clever plot twist

Self-righteous Brits? Sweet, I totally agree...

One of my bug bears is the endemic self-righteous nature of our tabloid press.
There are many great things in British culture, but we are as a nation becoming increasingly aggressive and abusive. There are many other problems: poor diet, cheap booze, drugs ... This is all very sad and the tabloids seem to be in denial, adopting a classic chav "aggressive defensive" posture. Rather than talk about real issues, they focus on celebrity, sports, and banging on about British superiority plus beating the Germans over half a century ago?
I was lamenting this point about "endemic self-righteous of the Brits" on the way back home, when an attractive young women (late twenties), with an Eastern European accent passed and called out laughing "sweet, I totally agree!"
Pero theatre trip






A Saturday with my mother and two nieces (10 and 8 years old)
The lunch went down well, for the main course:
1) a base of couscous and soya (no tumeric: Sophia has a phobia of all things spicy) with some veg (grean beans) and prunes
2) fried turkey breasts adding cashew nuts at the end (so as to soak up some of the juices)
3) pour into baking dish the "base" (couscous, soya, veg, prunes) and then add on top the turkey and cashews
4) bake/grill for 5 - 10 minutes
serve with pesto and/or sweet chilly sauce. Possible variations:
1) add pumpkin or sunflower seeds at the baking stage?
2) add walnuts or brazil nuts stage
3) spinach <-- delicious but not so good for children who like blander flavour
4) tuna or salmon stakes instead of turkey
The theatre was great, a stylish puppet theatre with operatic themes. The younger couple (washing girl & baker) were attractive, dance in a puppet like movement and sung nicely. They were slightly coquetish: very theatrical displays of legs and playful taps :) The pretty washer girl with curly brown hair had very rouge, which looked grat on her pale complexion. The baker looked slim, athletic and neat altogether a simple but vaguely handsome young man.
The older couple (the sun and the moon) were the music and song which drove the theatre. She had a very powerful, saprano voice, I expect she was an ex-opera singer. They played a wide range of instruments: keyboard, percussion, sax, ...
The whole arrangement had a rather traditioning Victorian style, there is little in this show which would have looked obviuosly out of place 100 years ago? Not so clearly visible there were: amplifers, spot lights, synthizer
For supper (with Mum & Nadjib), I did a nice salad: bed of spinach leaves, cherry tomatos, roasted figs (it is the season), asparagus, olives, feta cheese (cows milk?), rapeseed oil and balsamic vinegar.
Dinner with friends: Dawits, Stephanie, Emmanuelle and Nadjib



Aperitif: Champagne cocktails (dry pinot noir plus a few drops of sweet creme cassis)
Starter: Red and Green salad (peppers, cumcumber, tomatos, olives, asparagus)
Main: Coucous and turkey baked (plus sweet potatos, sunflowers, greens, farmhouse vegs, rapeseed oil, cranberries ...)
Wine: Chilean Red (muy bueno Cabernet Sauvigon)
Desert: Desert wine (nice Sauterne/Montbazillac) and chocolates
Halloween - the battered boyfriend!

Financial Crisis? How bad are things? "J'ai tort" Alan Greenspan

Following on from my blog entry last weekend, Nadjib has sent me another link to a credit crunch story. This time the article is in French, from the liberal paper "Liberation".
"J'ai fait une erreur en comptant sur l'intérêt privé des organisations, principalement des banquiers, pour protéger leurs actionnaires."
i.e. we can not blindly trust in free markets. Emphasizing the point he stresses that the markets (and himself) are in a state of shock:
"Ceux d'entre nous qui comptaient sur l'intérêt des établissements de crédit pour protéger les actionnaires (en particulier moi-même) sont dans un état de choc et d'incrédulité".
"La crise a pris une dimension beaucoup plus grande que ce que j'avais imaginé".
"J'ai trouvé une faille dans l'idéologie capitaliste. Je ne sais pas à quel point elle est significative ou durable, mais cela m'a plongé dans un grand désarroi."
"La raison pour laquelle j'ai été choqué, c'est que l'idéologie du libre marché a fonctionné pendant 40 ans, et même exceptionnellement bien".
"J'ai eu en partie tort en n'essayant pas de réguler le marché des Credit Default Swaps"
In brief a huge market for insuring against corporate bonds defaulting, in fact the CDS market ($50 trillion) has become much bigger than the actual corporate bond market ($5 trillion). Worse still these products, originally insurance tools have become highly leveraged, speculative products. If this market was to partially collapse (one big financial institution collapsing bring down another?) would it leave a financial black hole? Or have I mis-understood?
"Le modèle de gestion des risques tenait depuis des décennies. Mais l'ensemble de cet édifice intellectuel s'est effondré l'été dernier."
