Sam Riley and Garrett Hedlund in On the Road.

A cavalcade of stars shows up for this pretty, if meandering, adaptation of Jack Kerouac’s semi-autobiographical novel, On the Road.

Sam Riley (who was so damn good in Control) provides a decent center as Sal (essentially Kerouac). He finds himself on a long road trip that involves hand jobs from Kristen Stewart and him watching sex acts performed on Steve Buscemi. (Yikes!)

In short, this movie is a bit crazy, and its unpredictability keeps it interesting. Garrett Hedlund is solid as a character loosely based on Neal Cassady, and Stewart sheds her Bella image for a good, carefree performance. Others in the cast include Amy Adams, Viggo Mortensen and Kirsten Dunst.

The movie is OK, but I was looking for a little more meat on the bone, considering the subject matter.

On the Road is now available On Demand.
