Sydney Sweeney (Immaculate, Anyone But You) is set to star and produce via her Fifty-Fifty Films in Warner Bros.’ I Pretended To Be A Missing Girl.

Eric Roth (Dune, Forrest Gump) will adapt from the Reddit short story by Joe Cote. In the story, a drifter impersonates a missing girl to rob their family — only to realize she’s made a terrible mistake.

Vertigo’s Roy Lee, Steven Schneider, Trevor Engelson and Aaron Folbe at Underground are attached to produce.

Sweeney can be seen next in Paul Feig’s The Housemaid, Colman Domingo’s Scandalous!, David Michod’s Christy Martin biopic and Apple’s Echo Valley.
