On the heels of "This Is Not a Film" comes a second and far more resonant house arrest documentary, Marc Simon's "Unraveled," about the former New York litigator Marc Dreier, who funded the growth of his eponymous law firm with an exponential series of forgeries and impersonations, ending in his arrest and conviction on eight counts of securities and wire fraud. In 2009, between Dreier's guilty plea and sentencing, he was allowed to spend his last two months of freedom in his stripped-down Upper East Side penthouse, under armed guard and electronic monitoring, with only court-approved visitors and one landline.
