Toback's backbone of a script is great- it sets up the finest young actor of my generation (debatable- but worth saying) Downey Jr. is masterful in adlibbing and improvising. He accomplishes what Brando failed to do in Last Tango in Paris. Downey is real. His problems, his inner angst, his troubles all surface. This is like being with him. His magic and charm are entrancing and enchanting. Pretty cool. Worth a watch late at night- intense though.
