Lovelace, which features the Mamma Mia! beauty as the adult actress-turned-anti-porn advocate, premiered at the Utah independent movie event on Tuesday (22Jan13) and was warmly received by critics.
A reviewer for the Hollywood Reporter described it as ""surprisingly good on several fronts"", while a Screen International writer applauded directors Rob Epstein and Jeffrey Friedman for making the film ""both breezy and weighty at the same time"".
Lovelace, which chronicles the complex relationship between the Deep Throat star and her manager/husband Chuck Traynor - portrayed by Peter Sarsgaard, was promptly snapped up by The Weinstein Company's RADiUS-TWC division and will now be released in America this autumn (13).
Other popular picks at Sundance include Joseph Gordon-Levitt's directorial debut Don Jon's Addiction and Daniel Radcliffe's new film Kill Your Darlings, in which he portrays beat poet Allen Ginsberg.
Lovelace is the first of two new biopics about the former porn icon - actress Malin Akerman is also portraying her in rival project Inferno: A Linda Lovelace Story, although that film has stalled due to financing issues.
