Another Hollywood megastar is hoping his pen is mightier than whatever is currently keeping Costco in the chicken cooping business.

Following Ryan Gosling's letter-writing example last month, Brad Pitt has now lent his famed name to the cage-free cause, writing an open letter to the company's CEO, Craig Jelinek, on Thursday (July 16).

Pitt implored the wholesaler to stop marketing eggs from hens that have been "confined in tiny cages."

"These birds producing eggs for your shelves are crammed five or more into cages that are not large enough for even one hen to spread her wings," Pitt wrote. "In these cruel cages, the animals' muscle and bones atrophy from years of immobilization."

Pitt pointed out that the store chain has been proactive on other "positive social commitments" in the past, and asked the CEO to set a reasonable time frame for removal of the controversial products from shelves once and for all.

"I join Ryan Gosling, Bill Maher, and countless others in urging Costco to sell exclusively cage-free eggs," Pitt wrote, acknowledging his predecessors in the interest.
