Heart Beat (1980)

Synopsis
John Byrum wrote and directed this loosely based biographical tale of Beat author Jack Kerouac and Neal and Carolyn Cassady. John Heard stars as Jack Kerouac, and the film chronicles the Beat lifestyle that shaped the literary and social forces brewing and overflowing in Kerouac's imagination, resulting in the publication of Kerouac's seminal novel On the Road. Nick Nolte and Sissy Spacek play the Cassadys, enmeshed in a love-hate relationship that forms the backbone of the film. Kerouac drifts in and out of their lives as the Cassadys take up residence in San Francisco. Ray Sharkey is also on hand as the manic Ira, a thinly veiled character based on Alan Ginsberg. ~ Paul Brenner, All Movie Guide
