Carlo Ancelotti explained that he has no control over the left side of his face, which is why his left eyebrow can tuck up to a 30-degree angle.

“I cannot control my eyebrow,” Ancelotti said in 2016.

“Sometimes when I see an interview with me I am really surprised about my eyebrow going up without control. But there is no reason for this, no accident behind it,” he added.

Ancelotti has a unique facial expression that frequently makes him appear more serious than he actually is thanks to eyebrow movement.

Carlo's expressive face proved useful when he appeared in the 2016 film Star Trek Beyond.
