Jake Gyllenhaal and Carey Mulligan are attached to star in June Pictures’ “Wildlife,” written and directed by Paul Dano in the actor’s directing debut.

Based on the Richard Ford novel, the story tells the tale of a boy who witnesses his parents’ marriage falling apart after his mom finds another man.

“Paul is a natural born storyteller — a force. We are thrilled to collaborate with him and these phenomenal actors to bring his exquisite vision for this film to life,” said Andrew Duncan and Alex Saks from June Pictures.

The pic is produced by Duncan and Saks for June Pictures, and Gyllenhaal and Riva Marker for Nine Stories. Oren Moverman, Ann Ruark, and Dano will also produce, while Zoe Kazan and Eddie Vaisman are executive producing. WME Global handles the domestic rights to the film.

The script was co-written by Dano and Kazan.

“In Richard’s book I saw myself and many others. I have always wanted to make films — and have always known I would make films about family,” Dano said. “I couldn’t be happier to have such beautiful collaborators like Carey and Jake leading the way.”

The pic marks the first time Mulligan and Gyllenhaal have shared the screen.

Gyllenhaal’s most recent pic, “Nocturnal Animals,” premiered at the Toronto Film Festival and he is currently filming “Life” for Skydance. Through his Nine Stories shingle, Gyllenhaal produced David Gordon Green’s “Sronger”, in which he also stars.

Mulligan was last seen in the Focus pic “Suffragette” and most recently wrapped production “Mudbound” opposite Jason Clarke.

Both are repped by WME.

Mulligan is also repped by Julian Belfrage Associates, Ziffren Brittenham. Gyllenhaal is also repped by Carlos Goodman at Bloom Hergott.
