The review below of the film is as much about Ginsberg, himself, as the film, which is why I like it so much...

“I’M  COMING thru a stage of puberty and new horizons are opening up. ... I  am no longer bored by life in general because of my extra-curricular  activities. I haven’t the time to be bored.” The author of this diary  entry from 1941 is the famed American poet Allen Ginsberg who, at the  tender age of fourteen, vowed to never be bored, or boring, again. When  Time profiled the writer and his circle in 1959, the magazine mocked the  33-year-old poet as that “recognized leader of the pack of oddballs who  celebrate booze, dope, sex, and despair and who go by the name of  beatniks.” “
Howl,”  Ginsberg’s landmark poem and preface to the Beat generation, has been  called a lot of things since its publication in 1956—radical, visionary,  vulgar—but the one thing it’s not is boring. 
    Neither is  Howl the movie, co-written and co-directed by Oscar-winning  documentarians Rob Epstein and Jeffrey Friedman (The Celluloid Closet),  which opened last year’s Sundance Film Festival and stars James Franco  as the counter-cultural icon. The film is a composite of three  interlocking narratives: a candid interview with the writer on the  genesis of both his poem and his proud homosexuality; an incantatory  reading of “Howl” at the Six Gallery in San Francisco in the fall of  1955 (with Jack Kerouac and Ginsberg’s sexual muse, Neal Cassady, in  attendance); and animations by art director Eric Drooker, whose  hallucinatory renderings of the poem’s “angelheaded hipsters” and  “saintly motorcyclists” breathe new life into Ginsberg’s lines. There  are kaleidoscopic visions of copulating couples, saxophones that shoot  fire, and a graphic representation of what Ginsberg called the  “heterosexual dollar” in which the pyramidal eye on the dollar bill  explodes into scenes of childbirth and fellatio. This triptych makes  Howl less of a biopic than a genre that scarcely exists on the big  screen: a “lit flick,” an explication de texte, a work of literary  exegesis on film.
    Recreating the 1957 obscenity trial of  Lawrence Ferlinghetti for publishing Howl and Other Poems, Epstein and  Friedman stage a veritable round-robin of name actors: David Strathairn  for the prosecution and Mad Men’s Jon Hamm for the defense, along with  Treat Williams, Jeff Daniels, and Mary-Louise Parker as witnesses who  either defend or deny the poem’s artistic merit. Then there’s Franco, a  surprising choice to play Ginsberg, spurring Vanity Fair (Oct. 20, 2010)  to quip: “I saw the best movies of my generation destroyed by  miscasting.” Franco’s goyish glamour is indeed distracting—he’s a  veteran of the “Spider-Man” franchise and a Gucci model—but he  faithfully captures the poet’s north Jersey accent as he beds Jon  Prescott (as Cassady) and Aaron Tveit (as Peter Orlovsky, Ginsberg’s  lifelong partner) with all the playful tenderness that defined the  poet’s persona. Not your typical leading man, Franco recently appeared  in drag on the cover of Candy, a magazine devoted to what it calls  “transversal,” and in 2008 he played Scott Smith to Sean Penn’s Harvey  Milk. Coincidentally, Franco is enrolled in a writing program at  Columbia University, Ginsberg’s alma mater (from which he was suspended  in 1945). He told The New York Times (Sept. 12, 2010): “I’d have the  little book with me, and I’d listen to him, and I’d just read along with  him to just ingrain that voice in my head.”
    Howl poignantly  explores the writer’s irrepressible need to shock. Ginsberg, after all,  went to incredible lengths never to bore his lovers or his listeners.  When a heckler at a reading in Los Angeles in 1957 shouted “What are you  trying to prove?”, the author exclaimed “Nakedness!” and promptly  disrobed on stage. Howl the film examines this impulse from a more  personal angle, giving us those excruciating moments when Ginsberg’s  dirty jokes fell flat in front of his first loves, Kerouac and Cassady.  Catching up with the two after the road trip that inspired Kerouac’s On  the Road, Ginsberg spent what biographer Jane Kramer called in Allen  Ginsberg in America (1969) an “awkward month” with the pair, feeling  every bit the “lonely college boy who needed love ... and a lot of  attention.” Howl the film undresses that need, suggesting that nakedness  in both its physical and verbal forms was Ginsberg’s idea of  perfection. The film’s most revealing moment comes at the end when the  poet, fixing himself a cup of tea and reflecting on the cultural  movement he defiantly inspired, tells his interviewer that “Howl” is not  the “promotion of homosexuality” it was perceived to be, but a  promotion of honesty more generally. “When people are frank about  homosexuality in public, it breaks the ice,” says Franco in a  fake-looking beard, “then people are free to be frank about anything,  and that’s socially useful.”
