OTRC: Melanie Lynskey's 'Hello I Must Be Going' opens Sundance Film Festival

Melanie Lynskey is best known for playing dependable sidekick characters but the actress took the starring role in "Hello I Must Be Going," which opened this year's Sundance Film Festival.

In the film, Lynskey portrays a woman in her mid-30s who after being dumped by her husband, is forced to move back home with her parents (Blythe Danner and John Rubinstein) and begins an affair with the 19-year-old son (Christopher Abbott) of her father's business partner.

The pair go skinny-dipping, steam up some car windows and Lynskey sneaks into her younger boyfriend's room when his parents, who are under the impression he is gay, are out of town.

"It's really romantic," Lynskey told the audience after the premiere, reports Entertainment Weekly. "I was just in my hometown in New Zealand, and there's something about being back there that makes you remember all your first teenage romances and what they felt like and how strong those feelings were, and sneaking out and all that stuff. [The character] is 35 and was married, but she's experiencing all this stuff again at her parents' house."

"Hello I Must Be Going" was helmed by actor-turned-director Todd Louiso, who starred in "High Fidelity." Sarah Koskoff, Louiso's wife wrote the script.

"The story's about characters who take a back seat to others," Louiso told the Sundance audience. "[Lynskey and Abbott] play the people paying attention to the narcissists. Much like character actors, they're always in the background, giving their attention to the leads."

Lynskey made her film debut opposite Kate Winslet in the 1994 film "Heavenly Creatures" and portrayed the somewhat obsessive Rose in "Two and a Half Men."

The 34-year-old actress has also appeared in films like "Sweet Home Alabama," "But I'm a Cheerleader," "Detroit Rock City," "Up in the Air," "Ever After: A Cinderella Story," "Away We Go" and "The Informant!"

Her love interest in the film, Christopher Abbott made his feature film debut in last year's Sundance darling, "Martha Marcy May Marlene," which brought Elizabeth Olsen into the spotlight.
