Ray Liotta once received a not-so-subtle message from Frank Sinatra's daughters after a project didn't work out.

The actor recalled how Nancy and Tina Sinatra once mailed him a horse head while he was playing the late singer in HBO’s "The Rat Pack."

Liotta said on a recent episode of "Jay Leno’s Garage" that Nancy and Tina were developing their own TV miniseries about their father at the same time Liotta was making "Rat Pack" in the late '90s. 

"The daughters, they wanted me to do a miniseries when they were doing a miniseries about it and I just felt too uncomfortable," he explained about playing "Ol' Blue Eyes" in two separate projects.

After choosing the HBO movie, Liotta confessed, "We were doing the movie and I got delivered a horse’s head… Obviously, it wasn’t a real one, but it was a horse’s head. And, you know, a horse’s head means you’re toast."

The head is a nod to the famous scene in "The Godfather" when Luca Brasi (Lenny Montana) decapitates Jack Woltz’s (John Marley) prized racehorse and puts the bloody head in the movie producer's bed after not casting Johnny Fontane (Al Martino, rumored to be inspired by Sinatra) in a film. Fontane later gets the part and the gesture has lived on in pop culture history serving as a violent warning.

"It turned out that his daughters sent it and said, ‘Oh, you could do this one, but you couldn’t do the one that we wanted you to?’" he alleged.
