I didn't even realize until I read Thomas Gladysz's obituary of the man that the Roszak who wrote The Making of a Counter Culture is the same guy who wrote the novel Flicker. I read both books (about a decade apart) and simply didn't make the connection. Flicker is a really interesting thriller about the entirety of American film history, dark conspiracies, and murder. Reading it reminded me a little bit of the Illuminatus Trilogy, in that it was unabashedly huge in scope, perfectly willing to incorporate real historical events into a broad fictional canvas, and dense with puzzles and mysteries. I highly recommend it; it's an occasionally frustrating but entirely engrossing book.
