"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," the 34-year-old actor told reporters at the 40th Toronto International Film Festival.
The slider style fried chicken sandwiches from KFC were popular in the '80s and '90s and sold for only 39 cents.
"Anyway, 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 says.
After nearly 20 years off the menu, the Chicken Littles, now served with pickles and mayo, returned. When a reporter informed Gyllenhaal of this amazing news he smiled and said, "I think I indirectly had something to do with that!"
In his new film, Demolition, Gyllenhaal's character, Davis Mitchell, writes multiple complaint letters to a customer service representative of a vending-machine company (Naomi Watts), after losing his wife in a tragic car crash. Watch the trailer below to see a glimpse of his character as he becomes obsessed with his failure to purchase a packet of M&Ms from a vending machine in the hospital where his wife died.
Besides recently gushing over his love of food with reporters, Gyllenhaal told ET in July that being a father is something on his bucket list. "I am not a father yet, but it is definitely a dream of mine, should I be lucky to have that happen," he says.
Maybe Gyllenhaal and his future kid can bond over a delicious KFC meal someday!
