Edgerton will portray a man protecting his wife and son from a mysterious presence terrorizing them right outside their doorstep. David Kaplan is producing the film with A24, which is also distributing.
Shults wrote and directed “Krisha,” which won the SXSW grand jury award for narrative feature last year.
A24 acquired “Krisha” as part of a two-picture deal with Shults and released the movie in March with domestic grosses totaling $144,000.
Edgerton can next be seen in the interracial drama “Loving,” which Focus opens on Nov. 4. Focus bought the film, also starring Ruth Negga, for $9 million at the Berlin Film Festival.
Edgerton also starred in “Black Mass,” “The Gift” and “Exodus: Gods and Kings.” He made his directorial debut in “The Gift,” which he also wrote and co-produced.
He’s repped by CAA and attorney Bob Wallerstein. Shults is repped by WME.
