Tom Hiddleston appears to be losing his grip in a new “High-Rise” trailer released by StudioCanal through the actor’s Twitter feed.

The 75-second trailer, which includes portions of Tangerine Dream’s score from 1983’s “Risky Business,” portrays an increasingly troubled Hiddleston departing from an ordinary life to find himself in the middle of sex and violence.

“What are you doing in there?” a disembodied voice demands at the start and the end of the trailer.

Directed by Ben Wheatley, the thriller stars Hiddleston, Sienna Miller, Jeremy Irons, Luke Evans, Elisabeth Moss, James Purefoy, Reece Shearsmith, Peter Ferdinando and Dan Renton Skinner.

The film opens in the U.K. on March 18. Magnolia Picture acquired U.S. rights to “High-Rise” in December but has not set a release date.

“High-Rise” documents the outbreak of class warfare in a giant residential apartment block following a series of power outages. J.G. Ballard’s 1975 sci-fi novel of the same name inspired the film.

The film was produced by Jeremy Thomas. Executive producers are Peter Watson, Thorsten Schumacher, Lizzie Francke, Sam Lavender, Anna Higgs, Gabriella Martinelli, Christopher Simon and Genevieve Lemal. Nick O’Hagan and Alainee Kent are co-producers. Amy Jump, Wheatley’s wife, wrote the script. Film4 developed and financed the film.
