LOS ANGELES -- Ashton Kutcher as Apple co-founder Steve Jobs and Amanda Seyfried as porn star Linda Lovelace are among the highlights at January's Sundance Film Festival.

Kutcher headlines director Joshua Michael Stern's "jOBS," one of 18 star-studded premieres announced Monday for Robert Redford's independent-cinema showcase. Chronicling 30 years in the life of the Apple mastermind who died last year, "jOBS" is the closing-night film at Sundance, which runs Jan. 17-27 in Park City, Utah.

Seyfried has the title role in Rob Epstein and Jeffrey Friedman's "Lovelace," a portrait of the adult-film actress who became an anti-porn crusader years after starring in the hardcore hit "Deep Throat."

Other premieres playing Sundance include films featuring Scarlett Johansson, Dakota Fanning, Shia LaBeouf, Ethan Hawke, Holly Hunter and Naomi Watts.
