I ain't afraid of no ghosts. Except in the Paranormal Activity movies.
Back in the early '00s, Will Reiser was a twentysomething associate producer on the much buzzed-about HBO series Da Ali G Show, where he met and befriended then-newcomers Seth Rogen and his writing partner, Evan Goldberg. It was the beginning of one of those classic "rise up the Hollywood food chain" stories, until Reiser's momentum was derailed by an unexpected cancer diagnosis. To complicate matters further, the affected tumor was located on his spine and the risky surgical procedure that was required to remove it would be followed by a lengthy (and painful) recovery period. Reiser went through the diagnosis, the surgery and the recovery and now he's turned his cancer story into a semi-autobiographical feature film, with Joseph Gordon-Levitt playing his onscreen alter ego and Rogen as a character that's a thinly-veiled version of... Seth Rogen.
