Okay, there is this green lumpy drink that I have seen and I have been
trying to find out what is in it or where can I buy it premade. Rene
Russo is drinking it in the movie "The Thomas Crown Affair"  My guess
is it is a health drink with different grassesblended in it. I really
would like to find out where I can purchase it pre made or the
ingredients so I can make it at home.   ( It looks and probably tastes
horrible, judging by her facial expression when she drank
it.......lol)

Perhaps it's Bolthouse Farms Green Goodness Fruit Juice Blend.

From the Hipmama Forum:

"It contains: pineapple, apple, mango, banana, kiwi, spirulina, lime,
broccoli, green tea, spinach, barley grass, wheat grass, blue green
algae, Echinacea, garlic, star fruit, lemon, dulce and artichoke.

(..)

"But it tastes really good .. once you get past the green sludge color
and consistency."

(..)

"Did you ever see the movie The Thomas Crown Affair with Rene Russo?
She drinks these green sludgey looking things in that movie .. and
that's what this looks like."

I use a green, sludgy health drink which I get from my Yemenite herbalist.

It contains: gat leaves, olive leaves, and citron (etrog)juice

Wheatgrass juice?  It seems to be very popular at the moment in
Australia, usually drunk in the form of 'shots' (coz it tastes so
gross?!)
