Jim Belushi will join Keanu Reeves and Renée Zellweger on the cast of Courtney Hunt’s The Whole Truth, which has begun production this week in New Orleans. FilmNation handles international sales.

Also starring in the courtroom drama are Gugu Mbatha-Raw from Belle and Super 8’s Gabriel Basso.

“I’ve always been a big fan of Jim Belushi and am excited to bring out a side of him audiences haven’t seen before,” said Hunt, who earned an Oscar-nomination for her 2009 screenplay for Frozen River.

Reeves stars in The Whole Truth as a defence attorney facing a seemingly hopeless case as he strives to get his 17-year-old client acquitted of murder.

Basso will play the defendant, while Mbatha-Raw portrays a young attorney and Belushi and Zellweger are the accused’s parents.

“I’m drawn to stories that are as complex as reality and I gravitate towards actors capable of multi-layered performances who reveal the chaos and truth of life by reaching for those emotionally unexpected places,” said Hunt.

Likely Story’s Anthony Bregman produces alongside PalmStar Entertainment’s Kevin Frakes. Merced Media Partners co-finances the film with PalmStar and CAA represents US rights.
