A Scanner Darkly: According to Variety, Winona Ryder, Robert Downey Jr., Woody Harrelson and Rory Cochran will join Keanu Reeves in A Scanner Darkly, the Warner Independent Pictures drama that Richard Linklater will direct from his scripted adaptation of the Philip K. Dick novel.

Thesps will film the scenes as if this were a traditional live action undertaking, but then Linklater will turn the footage into animation, much as he did with Waking Life.

The tale concerns an undercover drug officer (Reeves) in the future who becomes addicted and develops a split personality. Novel was said to have been influenced by the drug experiences of the author, whose books have been the basis of such sci-fi films as Total Recall and Minority Report.
