Gyllenhaal, 34, said when he found out that his favourite item at KFC, Chicken Littles, had been taken off the menu, he wrote a letter to bring it back, reported Entertainmnet Tonight.
"I don't know if you remember: Kentucky Fried Chicken, when I was a kid, they had these things, (Chicken Littles)... like little hamburgers, but they were fried little chicken nuggets...
"They discontinued them, and in school, we were told to learn how to write a complaint letter, right? So I wrote a complaint letter to Kentucky Fried Chicken telling them (to bring them back)," he said.
When Gyllenhaal was informed by a reporter of the news, he smiled and said, "I think I indirectly had something to do with that!"
Gyllenhaal will be next seen in the drama "Demolition" along with Naomi Watts.
