Whanganui Film Society president Helen Marie O'Connell says next week's screening is not for the faint-hearted.
Wild is the third feature from actress-turned-director Nicolette Krebitz and returns from the 2016 NZ International Film Festival.
Not to be confused with the much tamer 2014 film of the same name starring Reese Witherspoon.
The film has an R16 rating and tells the story of Ania (Lilith Stagenberg), a 20-something office worker dealing with a creepy boss.
One day when walking alongside a wooded area near her apartment she locks eyes with a feral grey wolf.
"A walk on the wild side in the most literal sense, Wild is a wayward, confrontational, anarchic, sexually outré, modern fairy tale that balances on a razor-sharp edge between the genuinely provocative and the totally out-there," wrote Todd McCarthy of Hollywood Reporter.
"Nicolette Krebitz exhibits real nerve and rigorous control in equal measure as she tells a visceral tale of a young urban woman drawn to nature in a way that will shock mere tree-huggers.
"This will be beyond the pale for more sedate art house regulars but should develop a following among adventurous viewers hungry for the latest transgressions, especially in the realm of sexual politics."
Ms O'Connell says the film "will undoubtedly be our edgiest, most challenging film of the season".
Whanganui Film Society has changed slightly this year.
Full membership entitles admission to all 32 films in the 2018 season and is now $95 or $75 (discounted for returning members).
Half-year memberships (all films in either half of the year) are $50, and three-film samplers are now available for $25.
Youth under 18 years can get a full year's membership at a subsidised rate of $25 (less than $1 per film).
All membership types can be paid off by instalment.
Wild screens at the Davis Theatre, Whanganui Regional Museum, Watt St, at 7pm on Monday, March 12.
