EXCLUSIVE: Sam Rockwell has signed to star in Blue Iguanaa comedy feature from writer-director Hadi Hajaig, who last helmed the Charlotte Rampling-Sean Bean thriller Cleanskin. The project, which will be financed by UK Film Studio Productions, will start principal photography in London in July. Hajaig also produces with 3 Arts Entertainment’s Tom Lassally, who is also working on the Edge of Tomorrow sequel at Warner Bros.

An offbeat story about lying, stealing and shooting, Blue Iguana is described as a black comedy about two outcasts who fall in love in the strangest of circumstances.

“It’s a film that has a fun, naive and playful spirit that harkens back to movies like Jonathan Demme’s Something Wild,” Hajaig told Deadline from London. “It has a lot of action and a lot of violence, but it’s really a story about two people falling in love in very odd circumstances.” The filmmaker said he’s so happy that Rockwell is aboard. “Sam’s one of the most outstanding actors working today. Sam’s an actors’ actor who has strong comedic timing but also can turn at a flip of a coin into someone else. The role he plays is an outcast — as is his love interest — and when they meet, they spark each other. They come to life and end up doing things that they wouldn’t do ordinarily have done before.” The Blue Iguana refers to a coveted diamond.

Rockwell recently joined Woody Harrelson and Francis McDormand in Martin McDonagh’s Three Billboards Outside Ebbing, Missouri for Fox Searchlight and Film4. (The trio of actors previously worked together on Seven Psychopaths). Rockwell can currently be seen in Mr. Right opposite Anna Kendrick. Lassally is also an exec producer on HBO’s Silicon Valley, whose third season premieres April 24 on HBO, as well as an exec producer on IFC’s upcoming Stan vs. Evil from Dana Gould, which just got the green light in February.

Rockwell is a diverse actor with such varied roles in such films as Moon, Galaxy Quest, Confessions of a Dangerous Mind and Iron Man 2. He is repped by Gersh and Untitled Entertainment. Hajaig is repped by 3 Arts Entertainment.
